Where there is no DC welding machine,
lead-free tin bars for both AC and DC should be used. Metal elements are precipitated to form lead-free tin bars. The increase of other metal content and impurities will affect the welding effect of the lead-free solder bar and the oxidation speed of the lead-free solder bar is too fast, resulting in an increase in tin slag. When the copper content in the lead-free solder bar exceeds the specified lead-free solder bar The viscosity of the liquid tin will weaken the fluidity of the lead-free solder bar with the increase of the copper wall. Lead-free solder bar replacement.
Some lead-free solder bars are only suitable for welding at a certain position, and the effect is better when welding at other positions. Poor, and some lead-free solder bars are all-position electrodes that can be welded in various positions.
With the continuous innovation of their own products in electronics, IT, printing and other industries, the quality requirements of the auxiliary materials required for related production are also increasing; the performance of the products developed by the company and sold as agents have reached IPC-TM-650, IEC No Halogen standard and EU "ROHS" standard, suitable for all kinds of electronic products, printing production and other requirements.
