Use the quick test box to quickly diagnose surface problems of electronic components

During the production, storage, transportation and use of electronic products, the product surface is often susceptible to pollution, corrosion, oxidation and other effects due to natural or man-made reasons, causing many unexpected troubles. Invisible surface problems are like the unpredictable new coronavirus. To implement effective control, detection and investigation are crucial. ZESTRON® Flux Test, ZESTRON® Resin Test and ZESTRON® Coating Layer Test are portable rapid test kits specially developed by ZESTRON for common surface residues and conformal coatings on electronic components. Compared with other detection methods and instruments on the market, the three products have the advantages of portability, speed, accuracy, visualization and low cost, and have been favored by more and more customers in troubleshooting surface problems.

1) ZESTRON® Flux Test Flux Active Distribution Quick Test Kit

ZESTRON® Flux Test can clearly show the distribution of pollutants by means of color reaction, and identify the activator in the carboxylic acid type flux. It is a very important supplement for ion contamination detection and is conducive to the rapid evaluation of component reliability.

2) ZESTRON® Resin Test Resin Residue Distribution Quick Test Kit

ZESTRON® Resin Test can identify the distribution of resin residues on electronic assemblies by means of a color reaction. Timely detection of rosin or synthetic resin residues from self-fluxing fluxes during production and their removal by appropriate means can effectively avoid weakening of conformal coating adhesion and the occurrence of delamination.

3) ZESTRON® Coating Layer Test Rapid Chemical Test Kit for Coating Failure

The ZESTRON coating delamination test uses a color reaction to visually display coating defects, even for micron coatings. Whether the coating process is reliable depends mainly on the uniformity of the coating. This test can be used for low-cost sampling and monitoring during the production process to timely prevent failure risks such as coating voids or delamination, and reduce adverse effects on the final circuit board assembly.

In addition, ZESTRON R&S can comprehensively and accurately characterize and evaluate the sample surface through cutting-edge instrument analysis technology and rich experience in process technology and reliability, helping customers solve various complex reliability and surface technology problems. The technical means used by ZESTRON R&S include but are not limited to: high-definition digital microscope visual inspection, ion chromatography (IC), ion contamination test (ROSE), Fourier transform infrared spectroscopy (FTIR), coating reliability test (CoRe Test), particle measurement/technical cleanliness (Technical Cleanliness), scanning electron microscope/X-ray energy spectrum analyzer (SEM/EDX), X-ray photoelectron spectroscopy (XPS), Auger electron spectroscopy (AES), coating layer test (Coating Layer Test), flux test/resin test (Flux/Resin Test), contact angle measurement (Contact Angle), surface insulation resistance measurement (SIR), differential thermal analysis (DTA), etc.
