Soldermask opening is a crucial part of the PCB (Printed Circuit Board) design and manufacturing process. The main purpose of the soldermask is to prevent accidental flow of solder during the soldering process and to protect the board from the external environment. However, there are specific areas where we need to remove the soldermask in
I believe that many people will confuse flux paste with solder paste. In fact, they are different. Solder paste is tin paste. Its main component is a paste composed of metal alloy powder. But flux paste is different. It mainly plays a role of flux. Its main components are rosin, activator and solvent. A certain
With the rapid development of communication technology, high-frequency bandpass filters (HF Bandpass Filter) are increasingly used in wireless communication, radar, audio processing and other fields.As an electronic component that allows signals in a specific frequency band to pass through and suppresses signals in other frequency bands, high-frequency bandpass filters occupy an important position in modern
Wave soldering, also known as surge wave soldering, is a method of forming wave-like peaks through molten solder, so that the pads and component pins on the circuit board can be soldered as they pass through the peaks of the solder wave. The core of the solder tank is continuously heated and maintain a certain
In the pcba assembly process, welding is a key step in connecting various components together. In order to ensure the quality and effect of welding, pcba pre-soldering preheating becomes a link that cannot be ignored.
