Dendrite Failure – Causes & Cures Webinar

Industry News | 2018-03-24 09:45:36.0

Dendrite failure on printed circuit board assemblies is quite common but often not investigated fully to pin point the root cause. This is due to the intermittent nature of the failure or just replacing components seems to solve the problem Book at https://www.bobwillis.co.uk/event/dendrite-failure-causes-cures/

Why use Via in Pad Design?

Industry News | 2019-11-05 22:08:21.0

Via in pad is the design practice of placing a via in the copper landing pad of a component. Compared to standard PCB via routing, via in pad allows a design to use smaller component pitch sizes and further reduce the PCBs overall size. With component manufactures pushing smaller parts every year and the demand from consumers for smaller devices, the usage of via in pad practices by hardware engineers have become more commonplace. In this article, we will discuss the differences between via in pad and traditional vias, when should you use via in pad, and how to design for it.

Knowledge about PCB Panelization

Industry News | 2019-11-05 22:24:42.0

Designing a PCB for automatic assembly and full production runs requires a few design changes from an initial prototype PCB run. Today most PCBs are assembled and tested with automated machines from the data from PCB drawing files. With up to 80% of a new product's cost determined by the first prototype build, avoiding late changes and designing with manufacturing in mind can have a significant impact on the product cost, reliability, and yield of a PCB design. Luckily, if some good choices are made early in the design process, designing a PCB for manufacturing is relatively straight forward with few pitfalls.

Black stain... what causes it?

Electronics Forum | Thu Feb 14 17:40:34 EST 2013 | jorge_quijano

PCB Supplier made an EDX anaysis, the found a chemical trapped in the holes, and some burnt burrs, according to what they say this stains are over the solder mask & silk, so they do not affect functionality.
