All samples were scored with M 10 leaf blades, and then the samples were turned 90 ° and scored again * so that the cover layer surface was cut into a cross-sectional pattern containing 100 squares. Apply adhesive tape and rub Μ to determine a good contact, and then weep at a 90 ° angle with a smooth movement. The defect of the sample tested by 1 0 X magnification is generally detached or slightly broken. The removal of the cutting blade 2¾ is not considered a failure, but the removal of> 2¾ is a failed sample. Yingqu &amp; last seam The substrate used in this test is generally the MIT flexible tarsus pattern. The MIT pattern is a zigzag pattern with a variation of 1 mm line and space in the test area.

Copy the thickness and type of the substrate (copper, adhesive) and processing steps (pre-cleaning, bonding, hardening, solder exposure), so that the evaluation reflects the simulation of the authenticity. Generally, the Te c Lam-L F 9 1 11 etched on the side is subjected to mass transfer. R i s t ο η photoresist is coated on one side of the double-sided cloth, and the other side is etched with copper chloride using ammonia chloride feed solution at 5 8 ° C. The Ri s t ο η⑪ film was then exposed to the MI T pattern. The unexposed photoresist was developed in a 1% sodium carbonate solution ’and the exposed resist was stripped in potassium hydroxide solution to show the copper zigzag pattern. In 10 different areas of each sample, the vertical line and space will bend and bend the sample, and then use 10X magnification to inspect for defects such as cracking or detachment. Any reported defects are failures.

The durability of the test file is designed to measure the number of times the etched flexible printed circuit pattern is broken to failure after the processing of the K ghosting overlay. The samples evaluated are generally MIT bending durability patterns. The test pattern work has a 0.04 inch graphic in the center of 0.08 inch zigzag, and 6 patterns are produced in a 5 inch X 5 inch sample. The substrate used in this test is generally the same type as used in actual product applications, ie, the same thickness, type and thickness (copper, adhesive). In addition, the replicable photoimageable processing steps (pre-cleaning, lamination, hardening, solder exposure) make the assessment reflect real-life occurrences. The flexible durability was measured using a MIT folding endurance tester. The sample is connected to the device so that the sample bends perpendicular to the circular line.
