When thinking of creating a custom circuit board, you need to have the right tools at hand. Among the most essential of these is the assembly technique to be used. Conventionally, there are three circuit board assembler compliant techniques as detailed below.
 

Surfaces mount assembly technique - this involves soldering electrical components on the surface of a board. The technique is common in the soldering of metal tabs, fuses, and other components. For the best results, pre-soldering cleaning of the surfaces is essential for more permanent joints.

Box-build electro mechanical assembly technique - this harnesses custom designed metal factions, wire looms and molded plastics in the assembly of various electrical circuits. The technique is also usable in cable assembly for use in various electronic devices.

Plated through-hole assembly technology - this involves soldering various electrical components through the board from one end to the other. Although the technique is expensive, it leads to more reliable joints where every component is firmly soldered onto the circuit board. The components are first attached to holes drilled through the board before soldering is done. This is a professional circuit board assembler technique and should only be deployed in operational roles when you have adequate experience as to get optimal results.

When reworking an initially completed circuit board, it is recommended that you use the same assembly technique used by the initial designer.

This ensures that you get optimal results, while getting your circuit board restored to the initial condition with minimal damage on its surface. In cases where light weight but strong circuit boards are required, multilayered printed boards are recommended. Such boards are available in most stores, but can also be crafted in a highly controlled environment for use in various projects both at domestic and commercial levels. Multilayered boards are best known for their complex designs housing metrical interconnections between various components. As a result, this class of circuits is not recommended for less experienced circuit board assemblers.
