SMT red glue is the thrust of the original device in the PCB board after the use of force to calculate the tension force, the general tension is more show that the higher the viscosity of red glue, the better, the original device is not easy to fall off[Details]

Welding is a metal chemical bond is formed between the solder and metal, solder molecules penetrate into the substrate surface metal of molecular structure, and the formation of a strong, completely metal structure. When the solder melting, it is impossible to completely from the metal surface to erase it, because it has become a part of the base metal.[Details]

Red gum is SMT special monocomponent heat curing epoxy resin adhesive, with a storage stable, use convenient and fluidity of viscosity, temperature characteristics, good thixotropy, electrical insulation performance is good wait for a characteristic.[Details]
