You can get many types of contract electronic manufacturing services these days. The popularity of such service providers has increased because many OEMs or original equipment manufacturers have discovered that outsourcing their electronic manufacturing work, like PCB assembly for instance, to such contract manufacturers is more efficient and profitable. This is especially so when they are low on the resources needed to perform these tasks efficiently. Attempting to complete these manufacturing jobs, which require a high degree of accuracy and labor, in such adverse circumstances, will only reflect on the final quality of the work.

PCB assembly is an example of a manufacturing task that requires highly dedicated and skilled labor, as well as the right type of equipment ...
... and software to be done in an accurate manner. There are two types of PCB or Printed Circuit Board assembly jobs – PTH or Plated Through Hole PCB assembly and SMT or Surface Mount Technology assembly. PTH is the older technology of the two.

In plated through hole PCB assembly, the electronic components or leads that are to be affixed on a PCB are inserted into minute holes in the surface of the circuit board. In SMT assembly, the leads or components are mounted on, and not through the circuit board. They are affixed onto small pads or ‘lands’ that are made of tin-lead, silver or gold plated copper. In both PTH and SMT assembly, the leads are permanently attached to the board by using molten solder.

SMT allows you to attach more components to a circuit board than the PTH method, so it allows you to create smaller boards that are populated with a large number of leads. For that reason, it has become more popular than PTH. However, plated through hole PCB assembly is better for attaching components that needs to endure some amount physical stress. And there are components that are available in only either PTH or SMT packages, not both, so PCBs with both types of leads are used in most devices. Therefore, a good provider of contract electronic manufacturing services should be experienced in both types of PCB assembly.

PCBs are used in many different sectors and markets, and their specifications accordingly change. For instance, circuit board assembly is required in the sectors Security & Surveillance, Secure Data Transfer, and Power Monitoring, to name just a few. They can also be used in “high reliability” applications where they could be subjected to hostile environments, abuse and even attacks. You therefore have to ensure that the contract electronic manufacturer you hire is experienced in providing PCBs for these fields.
