Quality management – the number one topic at 4Source
As a distributor with multiple certifications, we undertake all possible quality assurance measures to minimise residual risks. This includes a complex rating and ranking system for suppliers, preferring sources who can supply full proof of origin (CoC), as well as the technical checks which every sold component goes through.
The goods receipt check is therefore based on the strict American IDEA standard, which stipulates a complex test cascade so as to rule out all imaginable sources of error.
Microscopy
Digital microscopy for counterfeit detection
“Don’t give fakes a chance!” It is not always possible to procure all components with full documentation of origin (CoC). A digital magnification check is therefore all the more important, especially in these situations. Experienced professionals at several microscopy workplaces identify even the slightest of abnormalities or manipulations. Samples of our overall goods turnover are checked routinely.
X-ray Inspection
In-depth testing of components by means of X-ray inspection
High-tech in quality assurance services. In addition to BGA and void inspection, optical error analysis, acetone testing, microscopy etc., all handled components are also routinely passed through the X-ray station. Every component is therefore put to “the acid test” and is compared with the relevant specifications and datasheets of the manufacturer. Potential fake components become evident at this point at the latest.
Photo Documentation
Intensive monitoring of the overall goods turnover
All incoming and outgoing goods are monitored in detail and are meticulously documented in image and text. As a result, a profound digital knowledge base has developed over the years, which also provides visual information about all components ever handled by 4Source, their condition and date code, model, labelling and packaging type, test results for quality assurance, proof of origin (CoC) and many more details.
Warehouse
Merchandise management, warehouse and logistics are fully ESD-protected
The entire warehouse is technologically as well as organisationally up-to-date. All workflows – particularly in quality assurance – are defined in detail, constantly optimised and also individualised based on customer audits. Merchandise management, warehouse and logistics form a closed, ESD-protected zone, which is accessible to trained and suitably clothed staff only.
