Abstract

The invention relates to the technical field of solder resist ink performance testing, and discloses a PCB solder resist ink performance testing method. The PCB solder resist ink performance test method comprises the following steps of substrate treatment, cutting, coating, pre-baking, exposure, development, secondary hardening and antioxidant treatment. Processing the substrate; according to the technical scheme, the plate is evenly cut into the base plates with the same size, then positioning holes are formed in the edge positions of the base plates, and finally the base plates are sequentially subjected to surface acid pickling, surface polishing and brushing, water washing treatment and drying. The plurality of substrates are used for experimental data collection and experimental operation, so that test items in one-time test are more sound, the performance test of the solder resist ink is more accurate, and proper solder resist ink can be selected according to requirements.

Description

technical field [0001] The invention belongs to the technical field of solder resist ink performance testing, in particular to a method for testing the properties of PCB solder resist ink. Background technique [0002] PCB board, also known as printed circuit board, printed circuit board, or printed circuit board for short, is cut into a certain size with an insulating board as the base material, and at least one conductive pattern is attached to it, and holes are arranged on it. The surface is covered with a layer of solder resist cured film, which acts as an insulation on the circuit board and is used to protect the circuit in the circuit board. [0003] The current performance evaluation test for solder mask ink in the PCB industry is not perfect, and most of them use scrap boards or a single test module for performance evaluation. Because the evaluation test items are perfect, it is not conducive to select suitable solder mask ink for production and processing according ...
