Anti-Corrosion Paints
Protection against moisture, salt spray and mildew, protecting the circuit board and related equipment from the erosion of the environment, thus improving and extending their service life and ensure the safety and reliability of use.
Three anti - paint a single component, low viscosity resins, the product is easy to operate: suitable for spraying, brush coating, dip coating, spray coating and other processes, curing speed, good adhesion to a variety of printed circuit boards.
It has good resistance to high and low temperature.Its curing in transparent protective film, with superior insulation, moisture-proof, anti-leakage, shock, dust, corrosion, salt fog, fungus, anti-aging, resistance to corona and nature other -sifat.
As a part of the manufacturing process of the circuit board, the reason for the ink plug hole is that the through hole made by the multi-layer circuit board to connect the circuit of the multi-layer board requires the ink to be blocked in the through hole after the through-line connection, so that the SMT and BGA will not have a short circuit during installation and will not hide dirt under the components after installation. The ink plug hole needs to meet the following requirements to meet the requirements, and there will be no hole explosion and hole explosion.
1: A certain amount of ink shall be reached in the through-hole to meet two-thirds of the hole depth.
2: The ink in the through-line hole cannot have bubbles, because there are holes and holes during heating, which will affect the performance of the product,
3: According to the requirements of customers, for example, some customers require the ink to reach a certain thickness and keep consistent with the board ink.
Ipcb has rich manufacturing experience in ink plug holes and can optimize PCB circuit boards according to customers' needs
