PCB is referred as printed circuit board that is mainly used to connect electrical component by means of electricity. The process of assembly is carried through etching from copper sheet that is laminated to create a non-conductive substrate surface. Specific PCB is filled with electrical components that are called printed circuit board assembly or in short PCB assembly. PCB is available in almost all the simplest electronic devices that are commercially produced. There are mainly two methods are utilized for PCB assembly first one is through-hole construction, while second one is surface-mount construction. In through-hole construction, component leads are inserted into the holes. However, in surface-mount construction, components are situated on pads, located on the external surface of the PCB.

In both types of construction, component leads are fixed mechanically and electrically to the board through melted metal solder. Nowadays, lots of companies are available that offer specialized Printed circuit board assembly services within the means of clients. Professionals utilize various kinds of soldering methods for connecting PCB components. For high amount production, mainly two types of soldering process is used first is machine placement and second is bulk wave kind. However, printed circuit board assembly carried for minute part is done under microscope.

Soldering is done with the use of tweezers and soldering iron, using a find tip that is designed for small volume prototypes. After soldering, professional applied conformal coating using dipping or spraying printed circuit boards assembly to provide finishing to assembly. This conformal coat prevents corrosion and the leaking of current or possible shorting due to condensation. Reliable dealer utilized highly sophisticated technologies for PCB assembly. In addition, it is static sensitive so, before delivery these products are placed inside antistatic bag. Printed circuit boards assembly involves multiple processes including PCB designing, creating PCB prototype, fabrication and others.

However, the type of components and process of assembly depends on the type of circuit board, kind of electrical component needs to connected and what electronic device the board is going to add. The process of PCB fabrication involves etching, engraving photos, multi-layer processing, drill, mask, finishing and finally electrical testing. After this PCB test is done to check its efficiency. There are two options for PCB turnkey assembly including full turn-key and partial turn-key.   Significant turn-key assembly services include ordering of all parts of PCB, online order tracking and management, assembly, quality inspection and final shipping. Reliable companies also offer free consultation and estimation about PCB assembly services and components. Moreover, you can also get full quote to decide you should proceed further or not.
