Understanding POFV in PCB Design

Understanding POFV in PCB Design

To achieve high-density wiring, shorten signal transmission paths, and enhance signal integrity, the via in pad is introduced. However, the design of vias in pads presents challenges for soldering. Since the vias are located within the pads, some solder may flow into the vias during the soldering process, leading to insufficient solder on the pads, … Read more

Advantages and Disadvantages of Common PCB Surface Treatments

Advantages and Disadvantages of Common PCB Surface Treatments

The main purpose of PCB Surface Finish is to protect the underlying copper layer from oxidation to ensure good soldering and electrical conductivity, and to continuously protect the solder joints from further oxidation after soldering. Below is a brief introduction to the advantages and disadvantages of common PCB surface treatment processes. 1. Bare Copper Board … Read more

DIY Reflow Soldering Station Using a Frying Pan and Arduino

MAKER: ThomasVDD / Translated by: Fun Without End Cherry Soldering tiny SMD components can be quite challenging, but this process can also be automated. It can be completed by applying solder paste and baking it in a (reflow) oven or hot plate (just like a cooking plate in the kitchen). I have seen many DIY … Read more
