PCB and PCBA Vendor

The PCB (Printed Circuit Board) is the layered board itself, without assembled components. PCBA (Printed Circuit Board Assembly) refers to the PCB itself, but with all components mounted. If you browse suppliers on some platforms, you will find many suppliers claiming to offer PCBA or  PCBA service. This signals that the supplier is not only making the printed circuit board itself, but can also manage Make pre-production prototypes, Procure components (i.e., CPUs and memory) from other suppliers, Manufacture the PCBs, Assemble the components on the PCBs.

PCB Assembly Process (PCBA Process) starts with a bare ready to assembly PCB. So, before we understand the Assembly Process in Electronics, it is important to understand different PCB materials used to make the base of a Printed Circuit Board.

 

A Printed Circuit Board (PCB) is can made of different heat resistant insulating materials. This base material can be Resin Based, Fiberglass Based, Epoxy Glass, Metal Board, Flame retardant (UL94-VO, UL94-V1), heat resistant plastic, kepton (For Flexible or Flex PCB) etc. Conductive copper tracks are printed or etched onto this con-conductive base substrate. The board is then coated with Green Mask and Silkscreen. Active and Passive Electronic components are then soldered onto this board either by Thru-Hole soldering Technology or SMT Technology or Hand Soldering, making it a Printed Circuit Board Assembly (PCBA).

Another major issue in using outsourced tech support and repair services is the parts being used.  It becomes difficult (if not impossible) to ensure that they're using nothing but the legitimate components you designed the device to utilize. For that matter, it's becoming easier for counterfeit parts to slip into supply lines without anyone noticing.  

 

When your manufacturer already has robust parts-tracking systems in place, this concern in greatly reduced. They'll be using the exact same parts that are on the assembly line, because they're usually in the exact same facilities as the assembly line.

 

PCB Vendor Producers

How to Find a Quality PCB Manufacturer? Find out what type of equipment your vendor is using. Producing higher precision electronics with fewer defects requires significant equipment investments. If you are looking for high yield complex circuit boards, your PCB equipment is critical. What about service? What is their response time like? Can you get someone on the phone? A tell-tale sign of quality service can be measured by the timely manner in which they get back to you. And lastly, references. If your manufacturer cannot provide actual testimony, look somewhere else. The proof is in the PCB, after all.
