The difference between wave welding and reflow soldering
Jan 04 , 2022
Wave soldering is a tin bar into a liquid state by tin slots, using a motor to form a peak, allowing the PCB to weld to the part, generally used in the hand-in-in-box soldering and SMT glue plate. Re-flowing welding is mainly used in the SMT industry, which is conducted by hot air or other thermal radiation, melting the solder paste printing on the PCB and welded. Different: Wave weld the flux, an...

Considerations on installing lightning straps and lightning protection network
Jan 04 , 2022
The lightning protection belt and its connecting line pass through a settlement ditch (settlement ditch: a long multi-storey building, which often divides the building into several sections horizontally, leaving a gap between sections to prevent inconsistent settlement of each section. When causing damage to the building), a spanning cable with an expansion and contraction margin of 10-20cm or mor...

Main methods to improve SPD reliability
Jan 07 , 2022
Product upgrading is the law of industry development. People usually pay attention to the performance and quality of the product, and often ignore the time quality of the product, that is, reliability. The launch of any new product should provide users with product performance quality, time quality, and economic indicators. The main methods to improve SPD reliability include: a. Manufacturers impr...

Backup integrated surge protector device
May 07 , 2022
Surge Protective Device (SPD) is a device used to limit transient overvoltage and discharge lightning current which can within the withstand voltage range, or discharge a strong lightning current into the ground to protect the protected equipment or system from impact. In order to make the surge protector operate safely and reliably in the power distribution system and prevent the oc...
