Abstract

This innovative solder head is robot controlled allowing non contact, uniform solder flow to all capacitor sites on circuit boards. Its compact heater design permits soldering of both single and double row products. Fluxing, heating and cooling are fully automated from a single mechanism whose simple design requires little maintenance support.

Capacitor Solder Head

This innovative solder head is robot controlled allowing non contact, uniform solder flow to all capacitor sites on circuit boards. Its compact heater design permits soldering of both single and double row products. Fluxing, heating and cooling are fully automated from a single mechanism whose simple design requires little maintenance support.

As shown in the drawing the Capacitor Solder Head assembly places and solders de-coupling capacitors on circuit boards. The magazine 1 holds four capacitors in a single row and a flux dispense assembly 2 automatically applies flux to the solder sites, prior to soldering. Cooling jets 3 built into the flux dispense assembly enhance solder solidification after soldering. Two nitrogen heaters 4 provide the heat source for reflowing the solder on the board. Two flange shaped heat tubes 5 are speci- fically designed to direct heat across the leads of four capaci- tors per cycle without interfering with adjacent rows of capac- itors. Thermocouples 6 are built into the heat tubes to control and monitor the heat that is being applied to the capacitors and boards.
