Six processes of gold-plating connector terminals

The stamped connector terminal is stamped by a die. The stamped terminal is only a material and must be electroplated before it can be used on the connector. Stamping connector terminal gold plating process classification: dip plating/micro dip plating, brush plating, spot plating, wheel plating, stick plating Ordinary dip plating: by adjusting the height of the positioning bracket in the plating tank, the depth of the plating part immersed in the plating solution is controlled to Obtain a predetermined gold-plated area. It can be used in combination with other processes to meet the requirements of more complex gold plating specifications. Mini immersion plating: The gold plating range is more targeted, especially suitable for the gold plating requirements of the SMT part of the terminal with a more complex structure. Compared with the ordinary immersion plating process, it can reduce the cost and waste of unnecessary gold plating area; it can also meet the gold plating effect that cannot be achieved by brush plating. Brush plating: This gold plating process is suitable for local selective gold plating of bumps or flat terminals. The partial surface of the plated part is in up and down contact with the brush plating platform. Under the action of the DC power supply, the metal ions in the plating solution are used to reduce and deposit on the predetermined part of the cathode plated part. Spot plating: This process is usually suitable for locally precision gold-plated products. According to the appearance and shape of the plated product and the requirements of the electroplating area, a special mold is opened in advance to achieve continuous and accurate electroplating of the specified parts of the product; this process has good electroplating quality and stability , The accuracy is high and the cost of gold plating can be avoided. Through the combination of molds, two-sided coatings with different specifications on multiple parts and surfaces can be obtained. Wheel plating: This gold plating process is suitable for partial selective gold plating or full gold plating of flat terminals (sheets). The non-electroplating area is shielded by the combined belt, and under the action of the DC power supply, the metal ions in the bottom spray liquid are reduced and deposited on the unshielded area of u200bu200bthe cathode plating part. Paste plating: This gold plating process is usually suitable for products with local continuity and precise gold plating. Use the plating equipment to paste a layer of special special material film on the area of u200bu200bthe product surface that does not need to be electroplated, and then combine with other gold plating processes (such as wheel plating, etc.) to achieve precise plating of the predetermined part (exposed) of the product. The process has good stability and high debugging accuracy, which can significantly reduce the cost and waste of gold plating in non-predetermined areas and provide a perfect plating appearance. Through the above process, the oxidation of the connector terminal products is prevented, the solderability is increased, the wear resistance is increased, the electrical conductivity of the circuit is directly improved, and the life of the stamped connector terminal is prolonged. It is a professional manufacturer of stamping parts, The terminal punching accuracy is high, the punching accuracy can reach plus or minus 0.01MM, and the punching speed is as fast as SPM1500.
