The purpose behind this procedure is to desolder and salvage cards from soldered cable assemblies using a hot oil immersion instead of a solder sucker or a solder wick. Removal of cards with such solder removal tools tends to splatter solder across the contacts causing shorts. Heat damage due to uncontrolled time also damages contacts and solder pads. The time spent on a rework is also longer since each wire must be removed individually. The hot oil bath is applied by immersing the entire soldered section of the card and when heated to the melting point of the solder, the entire cable can be removed from the card in one operation, leaving intact solder tabs. This method is applicable to any cable and card assembly using straddle mounted or single sided mounted terminals. 1
