    PCB Pitch: Ultimate FAQ Guide

    PCB pitch is also referred to as BGA (Ball Grid Area) in specific sectors. Although the manufacturer does not always consider the PCB pitch, it significantly influences your PCB’s effectiveness and, by extension, the performance integrity of your entire device.

    Few people have published PCB pitch information online. As a result, we get a large number of inquiries regarding this phrase from our customers.

    PCBMay, the biggest PCB maker in China, pays close attention to the pitch of its PCBs. To address that, we’ve chosen to compile a FAQ on this topic.

    What Is PCB Pitch?

    The pitch of a PCB is the distance between the centers of BGA pads, drill holes, and component connections. Fine pitch is defined as grids less than 0.7mm in size and copper structures less than 150 microns in size.

    The pitch size of an integrated circuit refers to the space between the solder joints (also known as pins) on the chip. The distance between two contiguous solder balls is determined from the core to the center of the other. The greater the pitch, the greater the amount of space between pads available for routing traces.

    The pitch of a surface mount (SMT) is measured as the distance between the middle of the pad of the surface mount and the edge of the pad.

    How To Design PCB Pitch?

    Current industry practice for containing a range of sophisticated and multifunctional semiconductor devices, including FPGAs and microchips, is to use PCB Pitch device packing, which incorporates the BGA part, to get the desired result.

    BGA packaging for the integrative framework has seen considerable evolution throughout the ages, with technological advancements of the chip makers in the market.

    To design your PCB Pitch, follow these steps:

    Identifying Appropriate Exit Routes

    The most challenging task for PCB designers in identifying appropriate escape pathways that will not result in PCB manufacturing failures or other problems.

    To guarantee an appropriate BGA fanout routing approach, it is necessary to consider many printed-board characteristics, including via and pad dimensions,  I/O pins numbers, layer numbers needed to fan out BGA, trace width separation, and trace width layout between pads.

    Easy Pad Access For PCB Pitch

    Finding The Required Layers

    Once a designer has established the overall space and trace width of the PCB layout, the dimension of the via, as well as the quantity of traces, they can compute the layer number required for the design.

    Certain vias are needed, and others are not. In most cases, the first two outer edges of the equipment do not need vias, whereas the interior portion of the device necessitates the routing of vias beneath it. The ideal practice is to limit I/O pins to reduce the number of layers on the board.

    This video will provide you with more information on PCB Pitch design.

    What Is A Fine Pitch In PCB?

    Boards having a substantially high number of items per square inch are often referred to as “Fine Pitch.” The elements on the board are packed, and the board’s design principles stretch the boundaries of PCB manufacturing tolerances to their maximum. These are also called “High-density PCB assembly” in certain circles.

    Typically, a high-density design would contain components with very tiny pitches, which would increase the cost of manufacturing and its capabilities. The smaller the element, the little its pads (as well as its physical body), necessitating the use of pick and place very precise devices. Assembling leadless components or including a grid array may need the help of X-ray inspection throughout the assembly process.

    How To Select The Components In PCB Pitch?

    The selection of parts for the PCB pitch is a vital step. The overall PCB performance improves with the improved component choices. Choosing the components has to be a very deliberate process for you. Simple errors may have catastrophic consequences for your whole equipment.

    When choosing the component of the PCB pitch, it is essential to keep the following points in mind:

    Before moving onto the PCB designing phase, the first stage ensures that the components chosen are small to allow for substantial board space savings during the placement phase. On the other hand, this method may wind up being a compromise of board room space savings and cost reductions.

    Generally, finer pitch devices, particularly those needing specialized types of inspection, like grid array-based ICs, are more expensive to fill throughout the manufacturing process (needs X-Ray testing). In the following image, you can see the IC’s pins separated by 0.3mm in pitch, which is compared to the size of a coin.

    Comparison Of PCB Pitch With A Penny

    Comparison Of PCB Pitch With A Penny

    The cost increases when tolerances are tightened; therefore, selecting more essential parts may be the best strategy if cost reduction is the top goal.

    Most integrated circuits are available in various package configurations. It is just a question of consulting the datasheets and taking these considerations into account while populating the design.

    What Is The Standard PCB Pitch Size?

    Pitch designs with a typical 0.5mm pitch have more breathing space than their smaller counterparts with 0.4mm pitches. The standard 0.5mm pitch provides about 19.7 mils of gap across solder balls when using solder balls of the same size.

    The average pad dimension is 8.7 mils, which allows you to direct traces between pads with 11 miles between them. The trace width of roughly four mils can be easily accommodated between two specified solder ball pads if the trace-to-solder-ball clearance is set at 3.5 mils between two soldered ball pads.

    You are restricted to about 220mA current via a 4-mil trace of 1oz copper (Cu) while utilizing a 4-mil trace. You can push 380mA via a 4-millimeter trace using 2oz copper. For a 0.5mm-pitch WLP, the gap and sizes are shown in the following picture. In the MAX8896 evaluation kit handbook, there is a WLP PCB layout with a pitch of 0.5mm.

    What Are The PCB Pitch Applications?

    Electronics, including kitchen utensils to cellphones to microwaves, are indispensable in our everyday lives.

    PCB Pitch plays a vital role in the contemporary world, serving as the main functional center with almost all electrical products. These tiny chips are available in an almost limitless number of combinations and are made from various materials.

    Medical Instruments

    Monitors: Electronic components monitoring devices like blood pressure, pulse rate, and diabetes monitors.

    Medical instrument: PCB Pitch is found in various medical equipment, including control systems, compressors, electronic microscopes, and so many more.

    Scanning devices: X-ray screens, CT scanners, and ultrasonic scanners all rely on electronic components to operate correctly.

    According to what seems to be the case, PCB Pitch is widely used in the healthcare industry. Even though medical PCB pitches are often smaller in size, their applications are many and varied. Looking around now, it seems that PCBs are present in a wide range of medical equipment, in contrast to previous years.

    PCB Pitch in Medical Devices

    Consumer Electronics

    The following are just a few instances of how PCB Pitch is often used in the area of consumer electronics:

    Computer Electronics: PCB Pitch is found in the cores of laptops and desktop computers, and it is used to connect them to external devices and displays, among other things.

    Mobile Devices: Tablets and smartphones are becoming more popular.

    Home and Entertainment system: Electronic components are used in various home and entertainment equipment, including alarm systems, coffee machines, and television sets.

    Automotive Use

    Cars used to be made up of just a few electrical circuits, but not anymore. Unlike previously, today’s cars depend on various electronics and digital elements for increased functionality. Here are several important PCB Pitches in vehicles:

    Proximity Monitors: Most modern vehicles have built-in sensors to assist drivers in estimating distances and detect blind spots. These systems depend on PCB and PCB Pitch to operate.

    Navigation: Cars are increasingly equipped with navigation systems. These systems work using PCB Pitches.

    Control Systems: PCB Pitches are used in advanced car control systems, including fuel regulators and engine management.

    What Is The Minimum Distance In PCB Pitch?

    Pitch is the distance between the centers of the wires on a PCB. With decreasing PCB pitch, wave soldering (the technique of connecting electronic systems to the PCB) becomes more difficult. Because wave soldering gets more complicated with smaller pitch readings, what is the bare minimum pitch spacing you should maintain on circuit boards?

    It is still feasible to get satisfactory results with pitches as small as 0.5mm if the proper controls are used (.0197″). Wave soldering faults can arise in pitches as little as 0.5mm, which is why we suggest using this as the bare minimum pitch for wave soldering a PCB.

    How To Drill Vias In PCB Pitch?

    Different kinds of vias are punched into a PCB Pitch based on their purpose.

    Through-hole vias

    The hole extends from the surface of the upper layer to the surface of the lower layer. Connections are created from the upper to the lower layers while using PTH technology. They can be classified as PTH or NPTH.

    Blind Vias

    The hole starts on the outside and finishes inside. The space here links the PCB Pitches exterior layers to one inside layer. The link is from the upper layer to the middle layer or from the lower side to the middle layer. After lamination, the opposite side of the hole is hidden. Blind vias are so named.

    Buried Vias

    These vias are within the PCB Pitch. Hidden vias have no way out. They tie together the inner layers while remaining out of sight. Buried and hidden vias should be no more than 150 micrometers (6 mils) in diameter, which is IPC regulation.

    Micro Vias

    The micro vias (vias) are the most widely used and recognized vias. HDI PCBs with high-density interconnection (HDI) often have micro vias included in them. Micro vias, more petite than conventional through-hole vias, are drilled by lasers during the manufacturing process.

    Vias In PCB Pitch

    Vias In PCB Pitch

    How To Stack-up PCB Pitch?

    The technology standards focus on the minimal SMT element pitch and allow trace, clearance, and PCB manufacturing costs. Complex high-speed designs using ball grid arrays often need 100/100 μm and 0.45/0.2mm (pad/hole) capability (BGA).

    Following these principles, compute the stack-up needed for the desired impedance (Zo) and divergent impedance (Zdiff). 50 ohm Zo, as well as 100-ohm Zdiff, are common.

    Remember that lower impedance increases dI/dt and hence current drawn. Higher impedance emits more EMI and exposes the design to external interference. Using less rigorous dimensions reduces costs and improves manufacturing yield. So, a suitable Zo range is 50-60 ohms.

    The number of layers needed for a design depends on its complexity. The number of signaling nets needed by a BGA, the additional supply required by BGAs, part density, and packaging types are also factors.

    Pitch 0.5mm and 0.4mm are becoming increasingly common. They need micro vias inside the BGA pad for inner layer routing. Not recommended on exterior layers are BGA pad traces.

    What is the PCB Pitch Manufacturing Process?

    If you want to build PCB Pitch for your product, doing this step will save you a lot of time and money in the future.

    1. Material preparation and examination

    Prepare the PCB Pitch, and whether there are any faults, take the test. Solder pads, which are flat copper pads lacking holes that are generally gold, silver, and tin-lead plated, are standard on PCB.

    2. Stencil preparation

    A stencil holds solder paste in a single position while it is being printed. It is manufactured by the planned locations of solder pads upon the PCB.

    3. Solder paste printing

    Solder paste, often a combination of tin and flux, connects the solder pads and SMC on the PCB and the PCB Pitch. Using the stencil and a squeegee, it is applied to the PCB at angles ranging from 45° to 60°.

    4. SMC placement

    It is then transported to pick-and-place devices transported on a belt conveyor, where the electrical components are put on the PCB.

    SMC Placement

    SMC Placement

    5. Reflow soldering

    A reflow soldering oven is used after SMC placement.

    The first zone of the oven is called the pre-heat zone, and it’s where the board and components are heated simultaneously and increased gradually. This section’s temperature ramp-up rate is 1.0°C-2.0°C per second to 140°C-160°C.

    The boards are soaked for between 60 and 90 seconds at 140 to 160 degrees Celsius temperatures.

    The boards move into a region that heats up between 1.0℃ and 2.0℃ per second until it reaches a peak temperature of 210℃ to 230℃. This is to liquefy the tin, which will help bind the element leads to the pads. The molten solder’s interfacial tension holds the components in place.

    A cooling zone guarantees solder solidifies at the heating zone’s exit, preventing frequent problems.

    This procedure may be performed on a double-sided circuit board utilizing solder paste or adhesive to keep the elements in place.

    6. Clean and inspection

    After soldering, clean the boards and look for faults. Repair any flaws and store the items. Magnifying glass, AOI, flying probe testing, X-ray equipment are standard testing tools.

    This video explains PCB Pitch fabrication and testing.

    How To Assemble Fine PCB Pitch?

    High-density applications often need fine-pitch components, affecting manufacturing costs and capabilities. Smaller parts need smaller pads (and thus smaller pick and place devices). When utilizing leadless and grid-array components, X-ray inspection may be required during assembly.
    Follow the procedures below to guarantee excellent PCB Pitch assembly:

    Component selection

    The first step before PCB designing is to make sure the components chosen are compact enough to conserve board space when placed. However, this method may save both money and board space.

    Component Ratings

    The grade of each component also matters for dense parts. Making a compromise here, too, with interest in more capacitors to take up space and reducing the total size of the package.

    Board Size

    Once the design and its constituent parts are complete, the second stage in an advanced PCB Pitch assembly project is establishing a suitable minimum board size.

    It may be necessary to include physical boundaries into the plans based on the size of the building and what it is situated on. With a “negotiable” dimension and the specifics still being worked out, this is somewhat easier.

    Component Placement

    Component positioning can begin when the design criteria and component capabilities are well defined, with components arranged closely to one another and adequate space for wires, holes, and planes. Essentially, this is hit or miss.

    It is wise to include the components, like the high-speed and high power parts, and the connections and other physical elements. It provides a structure from which to operate.

    PCB Component Placing

    PCB Component Placing

    Special modifications

    You may remove a portion of an element to create room for additional components. Extra metal shielding and features will extend from an element.

    Test points

    When designing high-density applications, keep in mind that every signal linked must test to a fine-pitch component. Test points are recommended to detect and repair any shorts, openings, parts positioned backward, or other anomalies. Mistakes may occur despite thorough inspection and testing, and catching them before shipment can save money and time.

    What Are The PCB Pitch Advantages?

    PCB Pitch provides you with a variety of advantages such as

    • Packaging with lower inductance.
    • Higher pin density
    • Lower thermal resistance,

    This implies more connector pins and faster performance than dual in-line.

    What Is The Difference Between BGA and PCB Pitch?

    Unlike Fine Pitch, BGA may utilize components for assembly if they inadvertently fall to the floor. The main benefit of BGA packages is their array structure, which provides more I/O per unit space than Fine Pitch parts.

    When I/O reaches 250, BGAs take up less space than Fine Pitch. Because BGA parts have a bigger pitch than Fine Pitch, they are easier to install and provide more power. The assembly rate of failure is also low on BGA.

    BGA Vs PCB Pitch

    BGA Vs PCB Pitch

    The most significant problem with BGA manufacturing is package defects caused by humidity sensitivity, missing soldering balls, and shipping collisions.  Double-layer solder balls and plating flaws like bad soldering among solder balls and part pads are possible. Because of this, BGA assembly has the lowest fault rate (ppm).

    The main flaw of BGA construction is its high cost. BGA packages have fewer leads than Fine Pitch and, therefore, better electrical performance than Fine Pitch. In terms of the substrate carrying elements, BGA is more expensive than Fine Pitch.

    In contrast, Fine Pitch carriers are made of plastic molding resin with a metal lead frame.  Comparatively, Fine Pitch and BGA packages need fewer packaging technical processes. With volume manufacturing, BGA package costs will decrease, but not as much as Fine Pitch.

    The most common BGA packaging with a large I/O pins count is the most expensive. There are no specified through-holes in packaging type. So the BGA bundle must bear the additional expense.

    However, the excellent assembly efficiency of BGA packages may offset their expensive cost. When I/O ports are less than 200, Fine Pitch functions well. Fine Pitch fails when I/O pins reach 200, and various BGA package types may be used, allowing BGA packages to be widely used.

    How To Test PCB Pitch?

    PCB Pitch testing is critical. You can avoid expensive failures and can save money by testing PCB before they’re put into products.

    Corporate PCB Pitch testing includes the following:

    In-Circuit testing

    This test evaluates the solder connection’s structural integrity. This is the most viable test for PCBs since it needs minor changes. The major drawback is the cost.

    Automated optical inspection

    After taking images of your PCB using a camera, a technician compares them to a standard schematic. The test will fail if your board does not match the design exactly.

    X-ray inspection

    X-rays may detect loose interconnections and soldering joints.
