Frequently Asked Questions (FAQ) About Our PCB Assembly Service Process and Capabilities

Here you will find many quick questions and answers about PCB Assembly Service,don’t hesitate to contact us,our email is sales@pcbmay.com.

A PCB populated with electronic components is called a printed circuit assembly (PCA), printed circuit board assembly or PCB assembly (PCBA). In informal usage, the term “printed circuit board” most commonly means “printed circuit assembly” (with components).

PCBMay is one of your best choices and we have one team who is responsible for components sourcing,PCB layout and manufacturing,assembly in house.

From the descriptions above, we can determine that the PCBA refers to a processing flow, or the complete circuit board while the PCB refers to an empty printed circuit board with no electronic components on it. Generally, PCB is a bare board while PCBA is the finished board.

The standard delivery time of PCB assembly is 3-4weeks.

Printed circuit board assembly is the process of connecting the electronic components with the wirings of printed circuit boards. The traces or conductive pathways engraved in the laminated copper sheets of PCBs are used within a non-conductive substrate in order to form the assembly.

We need Gerber files, Centroid data and BOM for your PCBA orders. As have already placed your PCB order with us, actually you only need to send the latter two if your PCB Gerber files have included the layers of silkscreen, copper track and solder paste. 

No,we can produce 1 to 10,000 pieces,what’s more,there is also no minimum order surcharge or additional fees

21st century is actually the era of science and technology. Because with every passing day, technology is making progress in a rapid pace. Moreover,PCB assembly service is playing basic and essential role in this development.

In fact, several devices and gadgets are upgrading at regular basis.And uses of PCBs in your complicated and simple electronic devices have become part and parcel.So,PCBA (Printed Circuit Board Assembly) service is basically the backbone of all electronic industries. Let’s read and explore more about the service of PCBA.

What is PCB Assembly Service?

PCB assembly is very important step in fabrication of the PCB. Whereas PCB stands for Printed Circuit Board. Furthermore,PCB is an essential component of each and every electronic device and gadget.

Basically, PCB is a thin board and designers make it from:

  • Composite epoxy
  • Fiberglass
  • Several other laminate materials.

There are different kinds of PCBs which PCB assembly service use them according to the needs of different applications. PCB provides a mechanical support for several different electronic elements.Moreover,electronic manufacturers are making use of PCBs for both purposes. Such as,

  • Industrial purpose
  • Domestic purposes.

On the other hand, PCBs are also providing mechanical support to all parts of electricity.

pcb assembly service 01

PCB assembly is basically the procedure of connecting all the electronic parts with the help of wirings of PCBs. Designers engrave the conductive traces or pathways in the sheets of laminated copper of PCBs. And so, they use them inside a non-conductive substrate to build a PCBA.

So, PCBA actually means the combination of PCB, electronic accessories and parts.

How Many Kinds of PCBs do Manufacturers use in PCB Assembly Service?

Generally,there are 8 types of PCBs which electronic manufacturers use in PCB assembly service.

In addition,these different kinds of PCBs are:

All the above PCBs are important and have different beneficial features. Moreover,electronic designers can use them according to the requirements of their PCBA.

Three Basic PCB Assembly Methods

PCB assembly is very important step in the fabrication of PCB.Moreover,it also includes all the other parts which are essential in order to create the complete PCB.

Electronic experts advise to execute the process of PCB assembly with great care,all precision and with a full attention. So that it can perform a successful operation of all the electronic devices.

Essentially electronic manufacturers use 3 methods to manufacture PCB assembly.Furthermore, these 3 methods of PCB assembly service are:

  1. Through-Hole Technique (THT)
  2. Surface Mount Technique (SMT)
  3. Electro-mechanical assembly

In addition,THT gives potential to all parts or components. While SMT is very helpful even in limited spaces.

Here is detail information of all these assembly methods.

Through-Hole Technique (THT):

In this process designers attach all components with the help of leads. In this kind of PCB assembly, they use PCBs with drill holes.So,it is very easy to assemble the components with PCB because leads are very easy to insert into drill holes.

Surface Mount Technique (SMT):

This technique had basically start in 60’s.Moreover,it had further developed in 80’s.And nowadays this PCB assembly service is widely using by several manufacturers of PCBA.In this process electrical designers include all parts with tabs of metal which they can easily solder to the PCB.

This is a very effective method of soldering.Moreover,this process provides densities of higher circuit and we can also fix the components at both sides of a PCB.  

Electro-Mechanical Assembly:

The other name of this assembly process is box-build assembly.In addition,this process makes use of the following elements:

  • Looms
  • Cable assembly
  • Wire harnesses
  • Molded plastic
  • Custom metalwork.

Designers use all the above elements to assemble electronic parts with PCBs.

Why PCB Assembly Service is Necessary for Any Business?

In fact,PCB assembly services are extremely precise and highly efficient and hence these are getting more importance in electronic manufacturing.They have become an essential part in mechanism and are performing an integral part.

Additionally,they are so important that electronics cannot even imagine to operate without them. These electronic appliances are:

  • Computers
  • iPods
  • Laptops
  • Calculators
  • Gaming machines
  • Television
  • Consoles and so on.

In this extra modern technological and digital world, use of PCBA has become essential and more significant because of its effectiveness and usefulness.Because electronic manufacturers use PCBs into electronic appliances and machines in order to connect parts or components.

Today newest generation is trying to explore the new exposures of microelectronics.So that they can lead the electronic packaging and engineering industry in order to innovate more and newer improve technologies.

So, only perfectly accurate and most effective PCB assembly service can sure that all electronic appliances will operate more precisely. And hence this generation is trying to explore perfect PCB assembly which will able to give absolute productivity.

Moreover,only a perfect PCBA service can give the electronic devices which will operate highly precision.

What is the Importance of PCB Assembly Service in Today’s Era?

As we have recognized the importance of using PCBs in electronic devices.Moreover,in complicated appliances and complex devices PCBA is extremely significant.Because they have ability to upgrade any digital appliance or device without any type of hassle.

PCB assembly has become part and parcel process in today’s business industry because of the extensive use of PCBs.Hence,PCB assembly service has got so importance in today’s technological era that we can’t imagine any progress without using it.

What are the Advantages of Using External PCB Assembly Service?

Here we are giving you some best reasons that why now every company is making use of PCBA service.

Saving of Labor Costs and Investments

Basically,PCB assembly service saves very large amount of labor costs and investments when you availing service from exterior firms. Moreover, there are lot of expenses in PCB assemblies. Such as it includes:

  • Setting up operations
  • Managing inventory
  • Hiring labor
  • Upgrading and maintaining all their facilities and many more.

When you get outsource PCBA service all of above tasks will be the responsibility of externals.

Focusing on Core Powers

When you decide to get benefits from externalPCB assembly service providers,your focus will at basic product developments and also on their basic competencies.In this way, you can easily increase competencies of your products. You can fully concentrate on many other activities. Such as:

  • Building of the brand
