PCB Cleaning (Cleaning of assemblies)

PCB Cleaning

As a manufacturer and system supplier kolb provides for the cleaning of assembled PCBs the complete process from a single source: including machinery, accessories, cleaners and specially applied software controlled fully automated electronic processes.

The cleaning of assemblies (PCB cleaning) is almost mandatory today, particularly in high-end area. These boards (assembled / mounted PCBs) must be cleaned thoroughly of production residues and possible environmental and handling dirt to ensure a reliable further processing respectively a trouble-free performance.

Especially where sensitive and thus mostly expensive modules are used, such as in the aerospace industry, the automotive industry, in medical technology or telecommunications, the assembled PCB cleaning is a full and important production step.

But even with the so-called no-clean manufacturing, it may be that these components must be cleaned to avoid malfunctions.

The thorough removal of flux residues, colophony, resin, oxides and soldering materials are the main tasks in the cleaning of printed circuit boards, active and passive electronic components, BGA, flip chip, relays, inductors, etc.

The cleaning of an assembly is not only a necessary prerequisite for reliable bonding and / or varnishing and so e.g. for climate security / avoiding current leakages. Assembled PCBs cleaning also allows debugging and so preserves the value of misprints and / or ensures the optical quality of the electronic components.
