Product Description: Shenzhen Hua Maoxiang electronic main R & D and production of solder paste, suitable for laser and iron rapid welding, after welding Wuxi beads and very few residual, bottom melting temperature solder paste is 138, 180 in temperature to the melting point, high temperature melting 217,, grain 25-45UM, 20-38UM, 15-25UM, 10-20UM. Applicable scope: camera module, VCM, CCM, antenna, hard disk, optical communication components, thermal sensitive element, photosensitive element and other traditional methods are difficult to weld products, improve assembly precision, and improve the efficiency of the assembling and welding, the welding equipment with laser and HOTBAR laser welding machine, the welding time is 0.3 to 0.6 seconds HOTBAR, the welding time is 5-10S minutes, the temperature is 160-300 degrees, high welding speed and high temperature, with ordinary solder paste flux component is about 11%, which is about 5% of volatile solvent, fast welding solvent volatiles will splash, splash online head welding position left a lot of balls and the residue, if not the following clean, easy to cause a short circuit. Fast welding process without solvent, no residue after welding solder, the solder balls can be saved to remove the continued. The product is a non halogen formula, the organic residue is very few, and it is transparent, the surface impedance is high, the reliability is high. The application process of dispensing, printing and scraping etc..
