SpletThis phase of the reflow soldering process needs careful supervision; Since accessing heat to the board and components may cause SMD patch components damage due to severe thermal stress, one must carefully watch this process. The temperature is recommended to rise at a pace of two to three degrees per second. Stage 2: Thermal Soaking Splet11. apr. 2024 · First, the hole wall is plated to make it conductive. Later, the barrel is filled with conductive (copper) or non-conductive (resin) material. The purpose of filling vias is to: Avoid the entry of any impurities. Hence, there is a lower chance of contamination or corrosion. Improve the mechanical strength of vias and pads.
