FPC Construction of Automotive Soft Panels

The FPC structure of automotive soft boards is generally treated on the surface to reduce oxidation, wear resistance, and compression resistance. It can be treated with tin, nickel, gold, rosin, etc. on the surface. FPC circuit boards have single sided, double sided, and multi sided structures. The size is 580mm * 580mm min, 1200mm * 450mm * * x, and the thickness is between 0.6mm and 2.5mm. It is made of polyimide material with many dense soft lines.



The FPC soft board process uses a thin film soft circuit board button made of polyacrylic resin, which can be used as a film. The use of high viscosity adhesive can completely bond the two interfaces. The surface of the plate is treated with gold plating, which has good surface gloss and strong pit oxidation. Special processing and production techniques are required, and circuit boards can be bent. Using soft acrylic lamination on the layout, it can be used as a welding film or to protect the outer circuit, with good insulation and conductivity on the surface. FPC board precautions: 1. FPC soft boards cannot be repeatedly bent, which can easily cause breakage. 2. Do not press down the membrane button forcefully without releasing it, as it can easily damage the soft acrylic protective layer or cause the switch to lose its original touch or even be damaged. 3. The operating temperature should not exceed 70 ℃, and the minimum temperature should not be lower than -20 ℃. It is best to use at room temperature to avoid affecting normal operation. During the production process, the heat shock temperature should not exceed 288 ℃, and the welding temperature should not exceed 230 ℃ (the welding time should be controlled within 3-5 seconds). 5. When powering on, pay attention to controlling the maximum voltage below 300V
