Plated through-hole (PTH) PCBs use copper-lined drilled holes for inserting and soldering component leads, providing superior mechanical strength and electrical reliability versus SMT. Key process steps include precise drilling, even heat application to lead and pad, and solder flow through the hole forming strong dual-side joints. Equipment includes automated drills, wave and selective soldering systems.

Reflow soldering in SMT assembly uses controlled heating phases—preheat , thermal soak , reflow , and controlled cooling —to form reliable solder joints. Nitrogen atmospheres reduce oxidation and improve wettability but increase cost and may cause tombstoning. Oven types include convection, infrared, and vapor phase, each offering precise temperature control tailored to PCB and component specs.

Flex PCB assembly means putting electronic parts on bendable materials like polyimide or polyester. These boards can bend, fold, or twist, fitting into tiny or tricky spaces. This bendability makes the flex PCB assembly process perfect for gadgets like phones, wearables, and medical tools.

Prevent costly PCB failures with in-circuit testing (ICT)—a method that tests each component directly on the board for fast, accurate defect detection.

Many individuals think of soldering as something that is done by professionals, but in reality, it can be an easy process to learn if you know what you're doing. In fact, there are many ways to do soldering on your own without having any special equipment or training. This article seeks to give you everything you'll need to know about lead solder vs. lead-free solder.

Flying probe testing, as its name goes, utilizes test probes that move from one test probe to another by flying. In this method, no custom fixture is needed which implies that it could also be referred to as a fixtureless in-circuit testing when used over an assembled PCB.

The process of PCB panelization is an important step in the PCB design process. Panelizing a PCB allows it to be broken up into smaller pieces to be more easily manufactured and uses materials more efficiently.

What are the standard PCB drill sizes? Can one find a customized solution based on the unique requirements? Yes, both standard PCB drill sizes and customized solutions are available.

The organic solderability preservatives, also known as anti-tarnish, are organic finishes installed on copper metal through a process known as adsorption. The role of this anti-tarnish is to prevent copper from being oxidized, picking up thermal shock, or being affected by moisture.

Quick turn PCB is a game-changer not only for manufacturers but also clients. It reduces the manufacturing time and saves money. The PCB prototypes can help avoid costly flaws by detecting issues that could go unnoticed until it's too late.

PCB Gold Fingers are the narrow, long, thin, and columned connections on the edge of a printed circuit board and whose purpose is to enable the board to connect with others.

A ceramic substrate is a type of material used in the production of electronic components. Ceramic substrates are typically made from alumina, zirconia, or mullite and can be found in different forms such as thin films, sheets, wafers, and more.
