Thorough cleaning of precision screens

As a manufacturer and system supplier kolb provides for the cleaning of printer screens the complete process from a single source: including machinery, accessories, cleaners and specially applied software controlled fully automated electronic processes.
Optimum screen cleaning (or cleaning of screen stencils, or stencil plates, as well as VectorGuard stencils) is a prerequisite for reproducible quality and low failure rates in both electronics and solar cell production today. Residues and contamination from SMD adhesives and SMD solder pastes on screens and stencils, especially in the apertures, lead to printing errors during PCBA production and thus malfunctions of the finished product.
In addition to cleaning stencils from adhesive and paste, this process can also be used to clean misprints (misprinted bare boards) as well as solder frames / solder masks and carriers of solder paste, conductive pastes, adhesive, flux, oil, grease or dust.
A couple of decisive questions have to be answered when designing a process consisting of machine, detergent and reproducible process control:
- Can the process effectively and material conserving clean fine and ultra fine-pitch apertures?
- What exact contaminations need to be cleaned now and in a foreseeable future?
- Can the process clean dry/older and fresh contaminations?
- Is the whole process environmentally safe and compliant?
- What is the total cost of ownership (investment, operating cost, maintenace time/downtime)?
