Via, also known as metalized holes, is one of the important components of PCB design. In double-sided and multi-layer boards, in order to connect the printed wires between the layers, a common hole, i.e., a via, is drilled at the intersection of the wires that need to be connected in each layer. Vias are divided…

Drawing panel fabrication drawings is an integral step in the process of making PCBs. Fabrication drawings for individual PCBs only show the drill holes and board features for a single PCB, but these need to be combined into one drawing for the entire panel. Depending on the specific needs of each company or manufacturer, some…
The measurement of PCB thermal resistance is a key step in evaluating the heat dissipation performance of printed circuit boards. Accurately understanding and measuring the thermal resistance of PCBs can help design more efficient heat dissipation solutions and ensure that electronic components operate within a safe temperature range. The following are several commonly used methods…
Introduction In today’s increasingly visual world, camera systems have become ubiquitous across countless applications – from smartphones and security systems to automotive applications and industrial machine vision.

1. Introduction Electromagnetic Compatibility (EMC) is a critical aspect of modern electronic design, ensuring that electronic devices operate as intended without causing or suffering from electromagnetic interference (EMI). Printed Circuit Board (PCB) design plays a pivotal role in achieving EMC compliance. Poor PCB layout can lead to signal integrity issues, radiated emissions, and susceptibility to…
The surface mount assembly process uses a stencil as a gateway to accurate, repeatable solder paste deposits. A stencil is a sheet or sheet of brass or stainless steel with a circuit pattern cut into it that matches the location pattern of the surface mount devices (SMDs) on the printed circuit board (PCB) where the…
We always say that the PCB is your critical component. With the growth of new technology-centric industries, this is true. One example in particular is lighting applications. LED lighting found in vehicles, urban infrastructure, and warehouses is evolving into a nuanced application that strives to bring precise brightness and color for perfect aesthetics. When it…
Water is bad news for an operating PCBA. Even small amounts of moisture can cause your board to fail, and avoiding moisture requires the best possible protection methods to be used. Even with this security, your board may still be vulnerable, as several PCB failure modes exist. To build a comprehensive defense, we first need…
Introduction Printed Circuit Boards (PCBs) are essential components in nearly all modern electronic devices, from smartphones to industrial equipment. Many PCBs contain small amounts of precious metals, including gold, which is used for its excellent conductivity and corrosion resistance. While the quantity of gold in a single PCB may be small, recovering gold from multiple…
