As an express service provider, safeguarding the production is an absolute priority. All the production lines and processes are under constant supervision. Every board gets an individual job ticket, which is compiled by a highly efficient, rule-based software.
In the production process, every step is recorded via barcoding. The traceability without any time limitation grants acces to all production lines, process sequences, operating personnel, production times, assembly and sub-assembly groups, as well as to all raw material and their batch numbers at any time.
Every employee is constantly trained for process sequences and technologies. As a confirmation for that, every employee owns a personal training certificate.
During production we conduct several optical and electrical tests, as well as visual and x-ray supported inspections on inner layers, assembly and sub-assembly groups.
|Microsection||layer thickness, etch-back, contacting, layer offsets, annular rings, insulation spacing etc.|
|Thermal stress||detached pads, lamination integrity, delamination, casing-, foil- and corner-cracking|
|Temperature change||change in resistance, electrical function|
|High voltage||dielectric strength of the dielectric medium and solder resist masks|
|Atmospheric change||to demonstrate insulation and humidity resistance|
|Tensile test||to demonstrate the copper adhesion to the base material|
|Impedance||AC resistance measuring|
|Bending cycle test||flexibility and permanent flexibility test of flexible circuits|
|Electrical corrosion||according to Siemens norm|
|Wet-chemical||various bath analyses|
|Transmitted light test||to inspect the chemical copper coating|
|X-ray||inspection of layer and drilling offset|
|Ductility test||to demonstrate the flexibility of galvanically isolated copper layers|
|Contamination test||to demonstrate surface cleanliness|
|Cross-cut test||to demonstrate the adhesive strength of solder resist masks after soldering simulation|
|Solderability||wetting test on drill holes and solder surfaces|
|X-ray fluorescence||to measure ultrathin metallic layer thickness|
