    The surface-mount technology is the most common electronic assembly way to fabricate the FR1 PCB components. In this technique, the PCB components are placed directly on the surface of the circuit board.

    The components like capacitors, LEDs, resistors, diodes, etc are inserted for conventional assembly. They have pins of different styles that create a flat contact with the PCB surface.

    The surface-mount technology increases the effectiveness of passive components assembly.

    Surface Mount Technology

    Surface Mount Technology

    Through-hole technology

    Another effective method is to mount FR1 components in through-hole technology.

    Where components are placed into the circuit through holes. Initially, holes are drilled on the PCB boards. These holes make a strong bond of components with the circuit board.

    Usually, the Connectors, Transformers, and Semiconductors are mounted using this through-hole method.

    PCBMay has services for both types of component mounting techniques.

    Does FR1 PCB Support High Voltage Components?

    Usually, FR1 circuit boards don’t support high voltage components. As the FR1 laminate is designed by cardboards that are suspected of electric shocks.

    Using high voltage components may lead to subsequent destruction and flaws of the circuit boards.

    How Is The FR1 Manufactured?

    To manufacture an effective FR1 PCB, you should have done 16 stages. Here we are going to discuss the complete manufacturing process of FR1 PCBs.

    Let’s dive in-

    Step 1 – Planning And Design

    The first and foremost step is the proper planning for circuit boards. Also ensures the appropriate environment for the PCB design and fabrication. Most generally, Gerber is used for circuit board designing purposes.

    It can encode necessary wording as well as check the algorithm to ensure there exist no errors in the code.

    Step 2 – File To Film

    Now it’s time to print out the design copy of the FR1 circuit board. PCB may use advanced technology for the filming process.

    You will get a negative photo of the design. The black ink defines the copper which is conductive. And the clear part indicates the non-conductive materials of the circuit board.

    Step 3 – Inner Layer Printing

    Then you should focus on the image of the copper path. Then create a figure on the copper foil. Now time to create the PCB laminate using epoxy resin and glass fiber materials.

    After that, use an alkaline solution to wash out the hard photoresist elements.

    Step 4 – Remove Unwanted Copper

    This time, the unnecessary coppers need to clean to get a spotless PCB board. Use a strong alkaline solution that is able to remove all unwanted coppers of the FR1 circuit board.

    Step 5 – Aline The layers

    After the cleaning process, you have to do the alignment of the PCB layers. The layers are pressed by the optical punch machine for the further fabrication process.

    Step 6 -Layer Up

    Now you should layer up the circuit layouts to create a strong mechanical bond. The fiberglass sheet is placed between the epoxy resin like a sandwich. Then covered by a copper foil for etching.

    Step 7 – Drilling Process

    In this step, holes are drilled on the stack-up layers in order to interconnect the layers. The diameter of the hole is an average of 100 microns.

    For the drilling process, the drill machine uses X-ray to create holes in the right place. That will help to produce more precise holes onto the FR1 PCB board.

    Step 8 – Plating

    Chemical deposition happens in the planting stage. For washing the board, chemicals are placed by using a deposition machine.

    Step 9 – Outer layer Imaging

    For outer layer imaging, the PCB board goes through UV light for a period. The UV light will not make any effect on the photoresist area.

    Step 10 – Electroplating

    The electroplating is done by a thin layer of copper then repeated in step 8 again. It helps to remove unnecessary copper foil from the circuit board.

    Step 11 – Etching

    After the electroplating process, the etching is done for the last time. That also protects the copper layer.

    FR1 PCB Etching

    FR1 PCB Etching

    Step 12 – Apply Solder Mask

    After planing and etching, the copper layer is coated with epoxy ink. Again the UV light is passed over the circuit to establish the solder mask.

    Step 13 – Surface Finish

    The surface finish is done in silver or gold. These both are considered as the best for PCB surface finish.

    Step 14 – Silkscreening

    In this step, the detailed information, test points, warning sign, taxes number all are placed on the FR1 circuit boards.

    Step 15 – Electrical Test

    The flying probe testing method is applied generally for the electrical test of the PCB boards. That test will ensure the quality standards of the printed circuit board.

    Step 16 – Profiling And V-scoring

    Here we have reached the final stage of the FR1 PCB manufacturing process. This time, cut the actual circuit board from the main panel. Then add the V-scoring, cut down the edges, and make them smooth as well as even.

    Watch this video to learn more about the PCB manufacturing process –

    What Is FR1 PCB Assembly?

    To assemble an FR1 PCB board, you should arrange and place the elements properly. The components may assemble by using the surface mount technique or through-hole technique. Essential terms for this PCB assembly are-

    Substrate

    The main material of the FR1 circuit board is the phenolic resin which is non-conductive.

    Copper

    Every PCB board has copper layers. They are very thin but used for conduction. The copper layers are placed at one side of the circuit board. That is considered as the active side.

    Solder Mask

    The solder mask is the surface layout of the FR1 PCB boards. It is like the insulator between the PCB layers. The solder mask also ensures the components are placed and operate in the right place of the circuit.

    FR1 PCB Solder Mask

    FR1 PCB Solder Mask

    Silkscreen

    The advanced FR1 PCB must have a silkscreen layer. It acts like the final layer having the letters, test points, high voltage warning signs, LEDs, numbers, etc. These all symbols are essential to identify PCB components.

    Manual Soldering

    In the manual PCB soldering step, the manufacturer can insert specific components through the holes according to the application demands. It’s a complicated circle and needs more time than the steps.

    What Is The Standard Thickness Of FR1 PCB?

    The FR1 printed circuit board thickness is like two or three credit cards. The standard PCB thickness is about 1.6 mm where the copper foil thickness is 0.2 mm. The thickness of PCB boards may vary based on the application’s requirements.

    Which Properties Affect The Performance Of FR1 PCB Materials?

    To get the higher performance FR1 PCB, you should be concerned about some properties of the PCB materials. The following factors affect the performance of the FR1 PCB materials.

    Decomposition Temperature (Td)

    If the temperature exceeded the required limit, there is a chance of decomposition of the materials. After cooling the temperature some materials can’t restore their initial stage.

    The FR1 materials can withstand 130 degrees Fahrenheit of temperature. So that the materials should have the decomposition temperature capacity.

    Thermal Conductivity

    The FR1 circuit materials must have thermal conductivity. When they come in contact with the conduct of heat, it needs to be transferred. The preferable thermal conductivity is 0.3W/Mk to 6W/Mk for FR1 circuit boards.

    Glass Transition Temperature

    The printed circuit board materials should have the glass transition temperature. The materials may be exposed during high temperatures, then able to come back at the previous stage. The glass transition temperature is 130 degrees Fahrenheit for FR1 circuits.

    Is There Any Difference Between FR1 and FR4 PCB?

    There are 2 fundamental differences in FR1 vs FR4 PCB. The construction material of FR1 PCB is phenolic resin where the FR4 PCB is made by the combination of epoxy resin binder and the woven fiberglass cloth. That makes FR1 circuit boards flame resistant.

    In addition, the FR1 is appropriate for single-sided circuit boards. And the FR4 is suitable for single to multilayer printed circuit boards.

    FR4 PCB Board

    FR4 PCB Board

    What Are The Differences Between FR1 With FR2, And FR3 PCB?

    The FR1 and FR2 PCB both are almost the same and work in a similar way. With FR3 the only difference is the construction materials. The FR1 is stacked up by cardboards where FR3 is made by an epoxy resin binder.

    FR3 PCB Board

    FR3 PCB Board

    What Are The Applications Of FR1 PCB?

    FR1 circuits provide a lot of benefits like chemical stability, high performance, lower price, etc. For these reasons, FR1 PCBs are used in thousands of commercial and industrial applications. Besides, FR1 is also considered the printed circuit component.

    For example, FR1 PCBs are used in telecommunication, consumer electronics like mobile, computer, remote devices, military accessories, medical sectors application, and so on.

    What Are The Specifications Of FR1 PCB?

    The permittivity, humidity, and heat treatment are the main FR1 PCB specifications. These properties must have certain values for unique FR1 circuit boards. Around 5.3 is the maximum value of permittivity. It will increase up to 5.8 when it is immersed in water.

    Again the humidity and heat resistance is MIN:5.0*103511.

    High Temperature FR1 PCB

    High-Temperature FR1 PCB

    Is FR1 PCB Moisture Resistant?

    The circuit boards should have a moisture-resistant capacity. Because moisture can cause short circuits or sometimes be responsible for component damage. The FR1 PCB offers around 1.0*1010 moist resistant capacity.

    Is FR1 Appropriate For Multilayer PCB Stackup?

    FR1 PCB is mostly suitable for single-layer circuits fabrication. For multilayer PCB stackup, FR1 is not appropriate. Even the FR2 and FR3 are not suitable for their low heat-resistant capacity. For multilayer PCB fabrication, you should go for FR4 PCB.

    Multilayer FR1 PCB Stackup

    Multilayer FR1 PCB Stackup

    What Is The UL 94 Rating Of FR1 PCB?

    The UL 94 rating of FR1 PCB is V-0. It defines the capacity of flammability as well as the maintenance of all safety standards. This rating indicates that the burning of the PCB materials stops within 10 seconds and there is no dripping allowed.

    The PCB manufacturer has a UL mark that is used to define the rating of the PCB boards. It also defines the performance, long shelf life as well as circuit reliability.

    How To Choose The Best FR1 PCB Manufacturer?

    The stability and durability of FR1 PCB depend on the materials as well as components mounting technique. The overall quality depends on the manufacturer’s technology and processes.
