Short answer:<\/strong> Plated stamped contacts should be quoted with wear and cycling evidence when repeated mating, vibration, or sliding kontak can change resistance. The RFQ should define plating stack, mating finish, normal force, wipe path, cycle count, environment, resistance limit, wear mark acceptance, sample stage, and whether inspection occurs before and after packaging or aging.<\/p>\n

A plated kontak can pass thickness inspection and still fail after repeated mating. Wear depends on kontak force, wipe path, edge condition, plating stack, mating finish, cleanliness, and environment. A meaningful RFQ connects those details to cycling and resistance evidence.<\/p>\n

Define the real mating event<\/h2>\n

Cycling tests are only useful when the test resembles the product. A bench test with the wrong mating blade, wrong angle, or wrong travel can produce clean data that does not predict field behavior. The RFQ should identify the mating part, insertion direction, wipe path, kontak force, and whether the assembly sees vibration or small motion after mating.<\/p>\n

If the kontak is supplied on reel or in trays, surface condition before cycling should also be controlled. Dust, fibers, oil, humidity, or rubbed packaging marks can change the result. For packaging-sensitive parts, use the tape-and-reel pocket orientation guide<\/a> to define no-touch surfaces and shipment evidence.<\/p>\n

Tie wear marks to resistance data<\/h2>\n

A wear mark can be acceptable if resistance remains stable and no base metal is exposed in a harmful area. A smaller wear mark can still be a problem if resistance drifts or debris collects on the kontak zone. The buyer should define both visual and electrical acceptance when kontak reliability matters. Keep failed samples, limit samples, and retained first-lot samples tied to lot labels so later complaints can be compared against the same evidence.<\/p>\n

Plating alternatives should be compared by function, not just cost. Tin, gold flash, silver, nickel, or selective plating can each be right depending on current, signal level, cycle count, environment, and mating finish. If the part has sharp edges or heavy wipe, review the edge condition with the kontak wipe edge radius guide<\/a>.<\/p>\n
