PCB Assembly Services – A Brief Introduction

You might have heard of PCB assembly services, but might not have any idea about this term exactly. Let’s make things simple for you to understand.

The entire procedure of manufacturing electrical devices is quite complicated and even time consuming. Materials play an important part in electrical manufacturing. These include silicon or other semi-conductors. By following numerous expensive and long clean room procedures, wafers are successfully converted into electronic chips and microprocessors. These chips are unable to carry out any job on their own. They are required to be integrated into PCB for carrying out activities like operating the phone or the computer.

There are many companies that deal in designing such chips but all these companies do not have the capability of buying all the tools needed for assembling the chips on to the PCBs for devising end-products. This job is carried out by the PCB assembly companies. Such companies possess many Surface Mount Assembly lines with services in the field of assembling PCB.

PCB assembling and fabrication companies offer their services to various companies who do not have any interest in carrying out such activities themselves.

The PCB Fabrication Procedure

The PCB fabrication procedure consists of a large number of processes and they are as follows:

·     Printing Solder Paste: This is the procedure during which the initial solder paste is successfully  printed onto the printed circuit board by making use of a stencil.

·       Pick and Place Assembly of SMT: This serves as the heart of the PCB line. The procedure takes  different individual chips and places them accurately at the right positions on the circuit board.

·      Through-Hole or Reflow Curing: Post placing the different chips on the solder paste, the circuit  board goes through a kind of conveyor oven for melting the solder and binding the chips onto the    PCB.

 There are many other small steps carried out in fabricating a circuit board. Shax Engineering is one of the  specialist manufacturers of different types of assembly fields for printed circuit boards.
