What is PCB Burn-in Testing? PCB burn-in testing is a reliability testing method used in printed circuit board (PCB) manufacturing to identify and eliminate early failures and defects in PCBs before they are shipped to customers. The goal is to stress the PCBs under elevated temperature, voltage, and/or current conditions for an extended period of time to accelerate aging and induce failures in marginal or defective components, solder joints, or the PCB itself. Burn-in testing Read more…

Introduction to Boundary-Scan Testing Boundary-Scan Testing, also known as JTAG (Joint Test Action Group) testing, is a method used to test interconnects on printed circuit boards (PCBs) or sub-assemblies. It involves using a boundary-scan cell to access and test the interconnects between integrated circuits (ICs) on a board without the need for physical test probes. This testing method has become increasingly important in PCB Assembly due to the growing complexity and density of modern electronic Read more…

Key Characteristics of HT-PCBs To be considered a true high temperature PCB, the board must have the following key properties: Substrate material with a glass transition temperature (Tg) exceeding 170°C. Common HT substrates include polyimide, ceramic, Teflon, and PEEK. Copper foil and plating rated for high temperatures, typically using rolled annealed or electrodeposited copper. Solder mask and silkscreen able to withstand the max operating temperature without degrading. High temp masks are usually made of silicone Read more…

Benefits of Custom PCBs Tailored to Your Exact Requirements The biggest advantage of custom PCBs is that they can be designed and manufactured to your precise specifications and needs. Some of the ways you can customize a PCB include: Board shape and size Number of layers Copper weight/thickness Solder mask color Silkscreen Surface finish (e.g. HASL, ENIG, OSP) Unique cutouts/holes By tailoring the PCB to your exact requirements, you can optimize the size, cost, and Read more…

Understanding Custom Cable Assembly Custom Cable Assembly refers to the process of designing and manufacturing electrical cables tailored to specific applications or environments. Unlike off-the-shelf cables, custom-made assemblies are built to precise specifications, taking into account factors such as length, connector type, shielding, and environmental conditions. The Importance of Customization In many industries, standard cable assemblies may not suffice due to unique equipment requirements, space constraints, or harsh operating conditions. Custom Cable Assembly allows for Read more…

What is PCB Burn-in? PCB burn-in, also known as board conditioning or heat soaking, is a process that involves subjecting printed circuit boards (PCBs) to elevated temperatures for an extended period. This procedure aims to identify and eliminate early-life failures, ensuring that only reliable and stable PCBs are deployed in the final product. Burn-in testing is crucial for PCBs destined for use in critical applications, such as aerospace, military, and medical devices, where reliability and Read more…
