Printed Circuit Board Assembly is the process of including the required components to a printed circuit board in order to form a full-fledged printed circuit board assembly. The construction of printed circuit board assembly involves two methods, viz. Surface Mount Technique (SMT) and Through-hole Technique (THT). SMT consumes less space, while THT provides strength to the component. So, both these construction techniques have their own advantages and disadvantages in the assembling process.
About the Assembly
PCBs basically use different conductive pathways, tracks and traces to connect different electronic components mechanically. All these components are carefully etched from laminated copper sheets and put onto the non-conductive substrate. The component leads are then carefully inserted through the holes in the circuit board in case of THT and placed on the external pads of the board in case of SMT. At last all the component leads are attached to the PCB by soft metal soldering. If products are manufactured in high volume, then bulk wave soldering is generally used. Machine placement and Reflow ovens are also used in the assembly process. Nearly every assembly unit is created using these techniques and equipment.
Significance of the assembly unit
Today, PCB assembly services are vitally important in the manufacturing of all electronic devices. There is a wide range of utilities of the assembly unit in this electronic and technological world. Electronic devices like computers, calculators, i-Pods, consoles, televisions etc. use assembly unit as an important integral part.
The assembly units have got a significant role to play in improving the performance of existing devices or gadgets. It either replaces the entire board with another assembly unit or works on individual parts of the unit.
There are many electronic manufacturing firms around the world providing printed circuit board designing and manufacturing services. The electronic manufacturers generally give the assembly manufacturing work to those firms on a contract basis since they cannot invest their workforce in assembly manufacturing. However, some large electronic manufacturers usually hire professional assemblers from reputable and authorized assembly services to manufacture large scale electronic devices.
PCB manufacturing and assembling
• Microprocessors and chips cannot do on their own. The process of building microprocessors and chips is itself a long and complicated process. But these chips, after they are manufactured, cannot perform their operations if they are not integrated onto the printed circuit board (PCB). So a PCB is an essential part of every electronic device.
