What is PCB Assembly?

PCB(Printed circuit board) assembly is the process of connecting the electronic components with the wires on printed circuit boards to make PCB work. The traces or conductive pathways engraved in the laminated copper boards of PCBs are used within a non-conductive substrate in order to form the assembly. 

Attaching the electronic components with the PCB is the concluding action before using fully operational electronic device.

 

Types of PCB Assembly

Printed circuit board assembly is advised to be done with carefulness, paying attention to details and absolute precision, as this would determine the successful operation of the electronic devices. The electronic machines can be ideally assembled with the PCBs in the following 3 ways:

 

Surface Mount Assembly(SMT)

The technique that emerged in the 1960s, and further developed in the 1980s, is currently being widely used by many PCB assembly manufacturers and hobbyists. The process includes components with metal tabs that can be easily soldered to the PCBs. The technique offers higher circuit densities when the components are fixed at both sides of the PCBs with effective soldering methods.

 

Advantages:

1. SMT, which doesn’t require drilling, is less mechanically stressful than thru-hole assembly.

 

2. SMT is a faster and lower cost manufacturing process than through-hole assembly.

 

3. SMT is the optimal assembly method for component-rich designs and allows for more connections per component than thru-hole assembly.

 

Disadvantages:

1. SMT-assembled PCB prototypes and component repair can be more difficult than on a board assembled by through-hole soldering.

 

2. SMT components are often not as high-powered or high-voltage as thru-hole components.

 

Plated through-hole technology (PTH):

This process applied for components with leads attached to them. PCBs used for this kind of assembly method always come with drilled holes.It is easy to assemble the PCBs with the components as the leads are effectively inserted into the drilled holes.

 

Advantages:

1. Thru-hole soldering provides stronger mechanical bonds than any other technique.

 

2. Thru-hole soldering is the optimal technique for connectors, transformers, electrolytic capacitors, and other heftier circuit board components.

 

3. Thru-hole soldering is considered to be the go-to process over SMT for many military or aerospace products.

 

Disadvantages:

1. Thru-hole soldering requires drilling into the bare board, which makes it a more time consuming process than SMT.

 

2. Thru-hole soldering is more expensive than using SMT.

 

3. Thru-hole mounting may not allow for as high a component density as SMT does.

 

4. Thru-hole mounting often requires hand-soldering, which is considered to be less reliable than the reflow ovens used in surface mount PCBA.

 

 

Mixed technology (SMT and thru-hole soldering together)

Advantages:

1. Usually, this method is used for more complicated boards where some surface mounting combined with some drilling. This technology would be best suitable for  a unique PCB layout.

 

Disadvantages;

1. Costs would be higher and lead time could be longer than normal assembly boards due to PTH components.

 

Electro-mechanical assembly:

Electro-mechanical assembly, also known as box-build assembly, which uses elements like wire harnesses, custom metalwork, molded plastics, looms, and cable assembly, in order to assemble PCBs with electronic components. This method is not commonly used in PCB assembly manufacturing process.
