Introduction to PCB Assembly Testing Printed Circuit Board (PCB) Assembly is a critical process in the manufacturing of electronic devices. It involves the placement and soldering of electronic components onto a PCB to create a functional circuit. However, the process doesn’t end there. To ensure the reliability and quality of the final product, it is…

What is a PCB? A PCB is a flat board made of insulating materials, such as fiberglass or composite epoxy, with conductive copper traces printed onto its surface. These traces connect various electronic components, such as resistors, capacitors, and integrated circuits (ICs), to form a complete electronic circuit. PCBs come in various sizes, shapes, and…

Understanding the Basics of High TG PCBs What Does “High TG” Mean? The term “TG” in high TG PCB stands for “Glass Transition Temperature.” This is the temperature at which the PCB substrate transitions from a rigid, glassy state to a more flexible, rubbery state. In other words, it is the point at which the…

What is HASL? HASL is a process that involves immersing the PCB in a molten solder bath, typically consisting of a tin-lead alloy (SnPb). The excess solder is then blown off the surface of the PCB using hot air knives, leaving behind a thin, uniform layer of solder on the exposed copper pads and through-holes.…

Understanding Impedance in PCBs Impedance is a measure of the opposition that a circuit presents to the flow of alternating current (AC) at a given frequency. In the context of PCBs, impedance refers to the characteristic impedance of the transmission lines, which are the conductive traces that carry signals between components. The characteristic impedance of…
