    Tips to Keep in Mind While Buying PCBA

    in General Discussions

    Before discussing what factors should be considered before buying PCBA, it should be learned what exactly is PCBA. And by definition, PCBA or printed circuit board assembly has many components assembled on a board like IC, capacitance, connector, resistance, etc. PCBA is found in almost every electronic device and machine. Ranging from mobile phones, laptops, to microwaves, to big vehicles like cars and trucks. It is a vital part of everything that requires electricity to work. Hence, it is important to know a PCBA and why it is important before considering purchasing it. An effective printed circuit board design is important. This is because it helps in the reduction of errors or short circuits. A good design also helps organize different wires attached because no one wants a tangled mess. Since PCBA is a vital part of electronics, it also contributes greatly to the world's technological advancements. That is why a good arrangement is important to prevent or avoid accidents.

    Now that it is explained what is a PCBA and why it is important, it is time to move on to the tips to keep in mind while buying a PCBA. While buying PCB assembly, it is very important to consider factors like material and mounting type. When an electronic device is built - cost, conductivity, managing space, heat, and ease of accessibility are important. So when it is time to fit in the circuit board, how it will fit, and the material used to design and construct it is important. So before purchasing, it is recommended to try free samples and find the solution for your appliance. And while using the free samples, look for the mounting type and the material of the printed circuit board assembly, or PCBA in short.

    Now there are multiple types of mounting types. They are:


    • Threaded Type - there are three types of threaded PCB mounting type; standard, held in one place with a nut, giving a secure fit that can be opened and tightened. Then we have the undercut that is more secure as it is fixed into the thread. Lastly, we have the self-tapping. This type does not need any washer or nut as it is fixed with self-tapping to the thread.

    • Snap-fit type pushes onto a panel or chassis hole and fix a strong mounting, making it easier for installation. There are three types of these fits - edge lock, bayonet, and fir tree.

    • Snap Lock Type - Pushes onto the panel but can be released easily.

    • Press Fit/Blind Hole Type - This mounting type is suitable for applications with space restrictions. Their fin-like edges hold on tightly to the binding holes, hence making it fixed in one spot.

    • Adhesive based - This type does not require a mounting hole, hence saving time and effort.
