PCB wave soldering assembly process

What Is Wave Soldering PCB Assembly

What Is Wave Soldering? Wave soldering is a classic THT soldering process used for mass PCB assembly production containing through-hole-technology components. In this in-line process, a printed circuit board is passed through a wave solder machine with the solder material pre-loaded in, and the machine controls the height of the standing molten solder wave as … Continued

Everything you need to know about PCB assembly conformal coating

A conformal coating is a type of thin polymeric film applied to a PCB (printed circuit board) by machine or by manual in order to have the electronic PCB boards and its components to be protected from the environment and corrosion. Normally, the film is applied at typical thickness of 25-250µm and ‘conforms’ to the shape of … Continued
