Measling occurs when discrete white spots appear in the base epoxy-glass laminate of a PCBÂ (printed circuit board), usually when the resin is not properly applied to the board during the lamination process due to the presence of moisture or other contaminants. Measling signifies a malfunctioning or poor-quality board that can degrade electrical and physical performance. […]

What are some of the most important factors you should consider when designing a PCB (Printed Circuit Board) to ensure efficient manufacturing? Consideration should be given to how the bare PCB will be supplied to the PCBÂ /Â PCBAÂ manufacturer for production. For volume manufacturing, the tools used throughout the process need âtooling stripsâ on at least two […]
With the increasing complexity of Printed Circuit Board (PCB) assemblies, it has become more common for surface mount components to be designed on both sides of the PCB. This provides challenges when automating the soldering of the through-hole components. Typically components that need to be soldered are done so using âWave Solderingâ (the preferred method), however this […]

Key points to consider when evaluating PCB manufacturers for your projects, include Quality Capability Cost Time Scale Manufacturer vs Broker Cooperation Material Sourcing Testing Quantities Choosing the right PCB manufacturer for your project and business will help you reach your goals, but choosing a wrong one likely will lead to much regret. Pointers to help determine your […]
PCBs, which are used in virtually all electronic devices, essentially routes electrical signals to satisfy the productâs electrical and mechanical circuit requirements. This is accomplished through a network of copper paths. To help prevent product designers from making unnecessary errors at least an awareness of the manufacturing complexities for PCBs is warranted. Step 1: PCB […]
PCB Assembly is the process of assembling various components like integrated circuits, capacitors, resistors, connectors, etc. on a Printed Circuit Board (PCB). Application of solder past to the base PCB. For surface mount components via use of a thin, stainless steel stencil & fixture solder paste is applied evenly over the solder pads in the […]
