Printed Circuit Board Assembly Technology

Right from their inception, assembly services have gained momentum and are considered as one of the most renowned services. Many companies are always on the look out for best assembling technology and services and manufacturers give the best of their services.

But before proceeding, let us first know about a PCB Assembly-

When electronic components are attached to a PCB, it is referred to as Printed Circuit Assembly. It is done only after a Circuit Board Assembly has been created completely. Various kinds of techniques are available to attach electronic components to printed circuit boards. Surface mount and through-the-hole technology are mostly combined on a single Printed Circuit Assembly. This is because of the availability of very few electronic components in surface mount packages.

Though, high volume production is executed by machine placement. Printed Circuit Assembly is used to connect and support electronic components mechanically. This is done by using conductive pathways or traces, engraved from the laminated copper sheers onto a non-conductive substrate.

There are three ways to create PCB assembly. Those are:

• Surface mount assembly - This technology emerged in 60s and evolved in 1980s. And now, it is widely used. In surface mount technology, components have metal tabs, and can be soldered easily to the board. Higher circuit densities can be achieved if components are attached on both the sides of the circuit.

• Conventional PTH Assembly - Plated through-hole technology includes components with leads attached. Thee components are inserted with the provision of drilled holes in a circuit board. This is an expensive technique; however it leads to the most efficient boards.

• Box-build, Electro-Mechanical Assembly - This technology involves the use of custom metalwork, wire harnesses and looms, cable assembly, and moulded plastics. All this is done to create Circuit Board Assembly.

But, no matter how robust your PCB Assembly design is, it is still prone to wear and tear. And the damaged or outdated parts of the PCB Assembly are not available easily in the market. In this case, it becomes necessary to avail Circuit Board Assembly services.

Hence, manufacturers should provide effective and efficient Printed Circuit Assembly service to their customer. This will not only keep the customers happy, but will also help the manufacturer to gain trust and goodwill in the market.
