How is PCB assembly done by EMS?

How is PCB assembly done by EMS? | Electronics | Scoop.it

Electronics and automation has overtaken most industries in the 21st century. Most industries depend on these devices for proper functioning.
There are many companies which take up the contract of developing these electronic devices. These companies are better known as Electronic Manufacturing Services or EMS. They design, manufacture, distribute, test and provide return and repair services for electronic components. They also provide assemblies for OEM or original equipment manufacturers. This whole concept is also known as Electronic Contract Manufacturing Services.
EMSs provide many services. Some are mentioned below.
•    PCB assembly
•    AOI
•    X-ray inspection
•    optical inspection
•    pin bed testing
•    Customized functionality testing
•    Surface Mount Technology assembly or SMT
•    Plated through hole assembly or PTH
The main assembling services provided by these Ems are PCB or printed circuit board. The electronic components are soldered to the printed circuit board for electronic assembly. The process used to perform the soldering is known as wave soldering or flow soldering.
The process of soldering is chosen because of the following characteristics:
•    The connection created by the solder is very reliable and clean.
•    The process re-uses the left over solder and flux.
•    The process is automatic.
•    Ensures efficient functioning and increased productivity
There are many machines available for carrying out the soldering process. However, all these machines work on the same principle. They have three zones: the fluxing zone, the preheating zone and the soldering zone.
The PCB first undergoes the fluxing process where the flux is applied to the underside of the board with the help of a fluxer. There are three different types of fluxers which are used: spray fluxer, foam fluxer and rotary fluxer.
After this process, the PCB enters the preheating zone. This zone consists of convection heaters which blow hot air to raise the temperature of the PCBs. Infrared heaters are used for thick PCBs. Preheating is necessary to activate the flux and remove any flux carrier solvents. It is also necessary to prevent thermal shock.
Next comes the soldering zone. The solder is usually a mixture of metals. Its chemical composition is 50% tin, 0.5% antimony and 49.5% lead .The molten solder is stored in a tank where the PCB is passed across a waterfall or wave of solder after loading it with the desired components. The connections are protected by solder mask, thus wetting the exposed metallic areas only. A trustable electrical and mechanical connection is then established. This process is faster than mechanical soldering.
After these processes are over, cleaning is done. It is done by solvents and deionized water.
Coating of the PCB is done after the cleaning. This protects the electronic components from external elements like moisture, chemicals, dust and extreme temperatures. Thus coating gives a longer life to the PCBs and is so considered to be a necessary step. The coating applied to it is conformal coating. It is done by various processes like brush coating, conformal coating dipping, spray application coating etc.
