Photosensitive polymer films are commonly utilized as a dielectric layer in microelectronics packaging. The performance of the organic film is determined by the adhesion quality between the polymer ...

A simple but effective way to double-check multi-coating finishes. Today, we see many different coatings being used in the same finishing processes, and I believe we need to be very careful that we ...

In my three preceding columns, I discussed the testing of sandwich panels as unit structures. This included flexural and shear testing of beams and panels. However, such tests — and hardware ...

Use the Gardco X-Cut template tool and cutter to perform the X-cut or cross-hatch test by making closely spaced cuts through the coating to the substrate. At least two cuts intersect at 90 degrees to ...

Adhesive forces play an important role in everyday consumer goods. Whether the product is a shipping tape, memo note, or glue, the adhesive’s strength and longevity determine the end users’ experience ...

Adhesion testers, both manual and automatic, measure the adhesion strength of coatings used on metals, woods, concrete and similar substrate materials. This strength can be determined by the analysis ...

Surface abrasion is a key predictor of long-term failure. Pilling at 10,000 cycles often predicts cracking, flaking, or delamination at 20,000–50,000 cycles. Pilling reduces slip resistance. A pilled ...

Silicone adhesives, along with primers, flame treatment, or plasma treatment, can be used to adhere low-surface-energy plastics to high-strength metals. For this article, several low-surface-energy ...
