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 ...

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 ...

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 ...

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 ...

The pneumatic 90° peel fixture was developed specifically for electrode adhesion testing. This peel fixture is designed to help an operator align and clamp down a specimen quickly and consistently ...
