1) Manual soldering iron tip temperature is welded parts in contact with each other and to the formation of tin solder temperatures required (ie, the actual solder point temperature or expertise can get the "welding temperature"). Generally expected that the temperature not higher than their melting point solder temperature 38 â„ƒ or 100 ° F, is appropriate.
2) Manual soldering time is the tip contact with each other and being welded parts and to the time required for the formation of solder joints (both in the welding tip at the time or expertise to stay "the Welding Electrode"). Should generally be controlled within 1 ~ 5 seconds is appropriate.
Welding time options:
1 ~ 2 seconds: small joints, thermal components, chip components (such as resistors, capacitors) and so on.
2 to 3 seconds: in the solder joints, paper-based or glass fiber based PCB, through-hole components, multi-pin mount device, such as lining of tin and lead.
3 to 5 seconds: large joints, glass fiber based PCB, solder, or heat dissipation, large area, and those who shield or a thicker wire and so on.
2, the solder wire diameter selection: 0.8 ~ 1.0mm: small solder joints, thermal components, chip components, multi-pin fine pitch placement devices. 1.0 ~ 1.2mm: in the solder joints, through-hole components, multi-pin, the large distance between the mounting devices, such as lining of tin and lead. 1.0 ~ 2.0mm: large spot, sugar tin, shielded wire, larger or faster ground heat, add tin Rework and so on. General solder pad diameter should be approximately equal to the direct 1 / 2.
Description: J350 is a low carbon iron core material for the Welding Flux of low carbon iron rod. DC reverse, flat welding and flat fillet welding performance is good, welding Arc force is small, shallow penetration, easy slag, weld appearance, weld metal has excellent crack resistance. Uses: dedicated to low carbon iron ammonia synthesis tower parts welding. With high-temperature hydrogen, nitrogen, ammonia corrosion, but also do crack and not the other requirements of the welding strength or transition layer.
