Short answer:<\/strong> Selective plating on stamped terminals should identify the functional zone, not just the metal finish. The RFQ should define kontak area, solder area, underplate, thickness, edge coverage, pre-plated or post-plated route, masking tolerance, exposed base metal limits, inspection method, and whether electrical, solderability, or corrosion tests are required.<\/p>\n

Selective plating is used when a terminal, kontak, busbar, shield, or spring clip needs a controlled finish only on certain surfaces. A gold or tin kontak zone may be needed for electrical performance, while the carrier, crimp area, or non-kontak body can use a different finish or remain less controlled.<\/p>\n

Selective plating decisions<\/h2>\n\n\n\n\n\n\n\n\n
Decision<\/th>\nWhy it matters<\/th>\nRFQ detail<\/th>\n<\/tr>\n<\/thead>\n
kontak zone<\/td>\nThe finish must be where the mating part actually touches.<\/td>\nMarked zone, working height, mating part, and probe location.<\/td>\n<\/tr>\n
Thickness and underplate<\/td>\nNickel, tin, gold, or silver systems behave differently under wear and heat.<\/td>\nMinimum thickness, underplate, and test method.<\/td>\n<\/tr>\n
Route<\/td>\nPre-plated strip and post-plating after forming have different edge coverage and cost.<\/td>\nCarrier design, forming severity, and exposed edge rule.<\/td>\n<\/tr>\n
Masking tolerance<\/td>\nMisplaced plating can waste cost or miss the functional area.<\/td>\nAllowed offset, boundary, sample photos, and inspection plan.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Mark the functional surface<\/h2>\n

The most important plating instruction is a drawing that shows where the circuit, solder joint, crimp, or ground path actually works. A broad note such as selective tin on kontak area can still leave room for disagreement. Mark the zone, boundary tolerance, side of material, and whether the formed edge or coined area is part of the kontak.<\/p>\n

If the part mates after forming, the kontak zone in the flat blank may not be the same as the final kontak zone. Carrier location, bend direction, burr side, spring height, and forming sequence all matter. For electrical acceptance, connect this to the kontak resistance and continuity test guide<\/a>.<\/p>\n

Choose route before quoting volume<\/h2>\n

Pre-plated strip can reduce post-process handling and support high-volume progressive paghulma, but the design must tolerate exposed cut edges and forming strain on the plated surface. Post-plating can cover formed features and edges better, but masking, rack marks, cleaning, and thickness variation can add cost.<\/p>\n

Selective precious metal plating can also change how scrap is valued. Ask whether the quote accounts for carrier strip, precious metal recovery, rejected lots, and first article reports. If the finish must survive handling or storage, review the cleanliness guide<\/a>, packaging guide<\/a>, and corrosion test guide<\/a>.<\/p>\n

If soldering follows plating, include shelf-life, bake history, and wetting evidence so the plating quote is tied to the actual assembly process.<\/p>\n
