Abstract
A novel composite electro-plating method is used for forming a composite plating layer based on chemical nickel with addition of a ternary alloy. The structure of the composite plating layer is formed by plating a copper substrate, plating the chemical nickel and plating the ternary alloy thereon. The electro-plating method includes following steps: ultrasound wave oil removal, electrolysis oil removal, water washing for 3 times, acid washing for neutralization, water washing for 3 times, electroplating of alkaline copper, water washing for 3 times, acid washing for neutralization, water washing for 3 times, electroplating of acidic copper, water washing for 3 times, activation, water washing for 3 times, electroplating of the chemical nickel, water washing for 3 times, activation, water washing for 3 times, pre-plating of the ternary alloy, water washing for 3 times, electroplating of the ternary alloy, water washing for 3 times, passivation, water washing for 3 times, hot water washing, blow-drying and air-drying. The novel composite electro-plating method greatly enhances the weather resistance of the product and prolongs the service life of the product.
Description
Technical field
The present invention is applied in the protection plating of radio frequency connector and microwave telecommunication devices, and the surface treatment protection of the metal shell of all kinds of outdoor use equipment.
Background technology
Due to the characteristic of communications connector outdoor application, the salt spray resistance demand of client is also more and more higher.Initial Military Standards is that 96H salt fog does not corrode, and by 2012, major customer common demands reached 24OH salt fog and do not corrode, and by 2013, has had customer requirement to reach 72OH salt fog and has not corroded.Subsequent request also can be more and more higher, even requires more than 1000 hours.Although the ternary alloy electric property generally used is better, 72OH salt fog cannot be reached and do not corrode; Powder injection process can meet 72OH salt fog, but non-conductive, and can only local complexity.The advantage that RP plating can well be merged ternary alloy and be dusted.
The process of communication connection product effects on surface has 5 basic demands below:
(1) can reach 72OH hour minimum, even require more than 1000 hours, existing plating and surface treatment means of defence cannot be accomplished; (2) radio communication simultaneously requires that coating is without magnetic, meets intermodulation requirement; (3) require to be electroplate with higher welding tin performance, convenient welding pcb board and wire rod; (4) environmental requirement; (5) with low cost, and there is production.Chromium plating, plating ternary alloy, dusts and anodic oxidation etc., but does not have a kind of plating mode can meet above-mentioned 4 requirements at present simultaneously, zinc-plated, and plating ternary alloy cannot Defend salt fog 72OH; Nickel plating cannot meet the demands (2); Dust, anodic oxidation cannot meet the demands (3), additive method also cannot meet above-mentioned five requirements simultaneously.
Summary of the invention
The object of the invention is, in order to provide a kind of novel composite plating method, to adopt multiple electroplating technology, requiring to complete same production line is disposable, owing to having multiple alloy and multiple coating, requiring the bonding force between each layer and consistency.
In order to achieve the above object, the technical solution used in the present invention is: a kind of Novel composite electroplating method, it is a kind of composite deposite adding ternary alloy based on chemical nickel, called after RP electroplates, and specification is at the bottom of first copper facing, then plates chemical nickel, the composite structure of ternary alloy is plated again above, its outward appearance is similar with ternary alloy, and surface is fine and smooth bright and clean, in stainless steel colored; Complete RP plating is made up of product ontology, copper plate and RP galvanization coating.RP galvanization coating is a kind of alloy layer, mainly containing elements such as copper, zinc, tin, nickel.
Its plating flow process is: ultrasonic oil removal, electrolytic degreasing, washing 3 times, pickling neutralization, washing 3 times, plating alkali copper, washing 3 times, pickling neutralization, washing 3 times, electroplating acid copper, washing 3 times, activation, washing 3 times, chemical nickel, washing 3 times, activation, washing 3 times, preplating ternary alloy, washing 3 times, electroplate ternary alloy, wash 3 times, passivation, washing 3 times, hot water wash, dry up, dry.
Compared with prior art, a kind of Novel composite electroplating method provided by the invention, substantially increases the weathering resistance of product and the working life of product.
Embodiment
A kind of Novel composite electroplating method, it is a kind of composite deposite adding ternary alloy based on chemical nickel, specification is at the bottom of first copper facing, plate chemical nickel again, the composite structure of ternary alloy is plated again above, called after RP electroplates, its plating flow process is: ultrasonic oil removal, electrolytic degreasing, wash 3 times, pickling neutralizes, wash 3 times, plating alkali copper, wash 3 times, pickling neutralizes, wash 3 times, electroplating acid copper, wash 3 times, activation, wash 3 times, chemical nickel, wash 3 times, activation, wash 3 times, preplating ternary alloy, wash 3 times, plating ternary alloy, wash 3 times, passivation, wash 3 times, hot water wash, dry up, dry.
Concrete detailed operation and management and control point see the following form:
Compared with prior art, the Novel composite electroplating method of a kind of economy provided by the invention, substantially increases the weathering resistance of product and the working life of product.
