Guangzhou wave plant, wave soldering factory in Dongguan, Shenzhen wave plant, Huizhou wave soldering manufacturers, Zhongshan wave plant, Foshan wave plant, specializing in manufacturing wave soldering, wave soldering the Friends of automation manufacturers, professional wave soldering plant, lead wave, small wave, a large wave has manufacturing. Refers wave molten soft solder (pewter), by an electric pump or an electromagnetic pump jet solder wave to the design requirements, it can be formed by the injection of nitrogen solder pools, making pre-loaded components PCB via solder wave, soft soldering or welding ends between the components and the PCB pad pin mechanical and electrical connection. The machine used in different geometries crest, wave soldering systems can be divided into many species. Wave soldering process: the element into the corresponding holes in → precoat element flux → pre-bake (temperature 90-1000C, length 1-1.2m) → Wave (220-2400C) → removal of excess widget foot → Check. Reflow soldering process is by re-melting previously allocated to the PCB solder paste solder pads, soft soldering surface mount components between the pin and solder terminals or PCB pad mechanical and electrical connections . Wave as people's awareness of environmental protection, a new welding process. Before the tin-lead alloy, but the lead is a heavy metal on the human body great harm. So now with lead-free production. It uses a tin-silver-copper alloy * * and special flux and solder bonding temperature of demanding higher preheat temperature also like to say that after the PCB board by welding area to set up a cooling zone workstation. This aspect is In order to prevent thermal shock on the other hand, if there is, then ICT will detect an impact. The most unwanted miniaturized products still in use perforation (TH) or mixed technology circuit boards, such as televisions, home audio and video equipment as well as the upcoming digital set-top boxes, still are perforated element, so need to use the crest welding. From the process perspective, wave soldering machines can only provide very little basic equipment operating parameter adjustment.
