PCB Assembly And Manufacturing: Common Mistakes in Component Selection.

The manufacture and assembly of printed circuit boards (PCBs) involves multiple steps that are performed in a rigorous and demanding manner to achieve the desired results. Today, automated equipment is used in PCB assembly and manufacturing, which helps to minimize errors in the design and manufacturing process, reduce production costs, reduce product recalls, and reduce time-to-market. The success of any PCB assembly depends on various factors such as product design, component placement, testing and inspection, etc. Although these factors have been discussed many times, there is one that is often overlooked - choosing the right components.

Component Selection: Understanding the Different Steps Involved

Although component selection sounds simple, there are several considerations involved in this process. To gain clear insights, the process can be broken down into three steps:

1. Component selection: This is the most important step in PCB manufacturing and assembly. PCB assemblies utilize a variety of active and passive components. Vacuum valves, triodes, transistors and tunnel diodes are some of the active components. These components power the circuit and can amplify the signal. Active components draw power from a power source. Passive components are components that cannot induce power in a circuit, they do not depend on any type of power source. Inductors, transformers, capacitors and resistors are some examples of passive components.

2. Purchase parts: This involves purchasing or purchasing parts for the assembly. Due to various factors, such as supply shortages, high prices, unavailability of required components, etc., the procurement or procurement cycle of components may take longer than expected.

3. Placement of components: The above two steps ultimately lead to placement of components, which is a key step in PCB manufacturing and assembly. Although largely automated, there are several considerations involved in this process. The performance and success of the PCB largely depends on this stage.
