Zinc sulfide bulb can conductive ring lead welding method

By using the angled tip of a temperature-controlled soldering iron to melt the bottom solder on the copper film of the conductive ring and cover the lead connector, combined with flux and silicone rubber protection, the problem of insufficient lead soldering strength was solved, achieving the effect of not falling off under 10 Newtons of tensile force.

AI Technical Summary

Technical Problem

When welding leads onto the zinc sulfide ball-shaped conductive ring, existing technology makes it difficult to guarantee the welding strength between the leads and the copper film of the conductive ring, which leads to the leads easily falling off after welding.

Method used

The beveled tip of a temperature-controlled soldering iron is used to melt a base layer of tin onto the copper film of the conductive ring and spread it flat. Then, the molten tin is taken through the beveled tip and soldered to cover the lead connector to form a solder joint. After cooling, the solder joint is protected with flux and silicone rubber.

Benefits of technology

This technology enables the lead wire to withstand a tensile force of 10 Newtons without detaching after welding with the copper film of the conductive ring, thus improving the welding strength.

Abstract

A method for welding a lead of a ball cover conductive ring of zinc sulfide includes the steps of: S1, before welding, wiping the surface of the conductive ring copper film clean; S2, using the inclined plane of the iron head to melt the bottom tin on the surface of the wiped clean conductive ring copper film, and then laying the bottom tin on the area of the surface of the conductive ring copper film corresponding to the position of the welding lead; S3, after the laid bottom tin cools to room temperature, using a preheated temperature-controlled electric iron to take the molten tin solder, so that the molten solder covers the welding joint of the lead and coats the outer peripheral surface and end surface of the welding joint, and then allowing the solder coating the welding joint to cool; S4, after the solder coating the joint cools, laying the welding joint of the lead coated with solder on the bottom tin, taking flux, and pressing the solder coated by the welding joint of the lead with the inclined plane of the iron head, so that the solder coated by the welding joint of the lead is fused and connected with the bottom tin, forming a welding point; S5, after the welding point cools, using silicone rubber to glue and cover the welding point for protection.
