Continuous gold plating process classification of connector stamping parts

The connector stamping is made by stamping with a die. The stamped terminal is only the material and must be electroplated before it can be used on the connector. The following is the decomposition of the gold plating process. Gold plating process classification: dip plating/micro dip plating, brush plating, spot plating, wheel plating, stick plating. Ordinary dip plating, usually used for electroplating Gold Flash products. By adjusting the height of the positioning bracket in the plating tank, the plating parts are controlled to be immersed in the plating. The depth of the liquid 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 complicated 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. The groups of electroplated terminals suitable for connector stampings are as follows: 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. A single device can realize single-sided partial gold plating, or multiple units can be used in combination to meet complex gold plating requirements. This process adjusts the gold-plating position according to the 'Electroplating Engineering DrawingThe groups of electroplated terminals suitable for connector stampings are as follows: Spot plating, this process is usually suitable for local precision gold-plated products. According to the appearance and shape of the plated product and the requirements of the electroplating area, special molds are opened in advance to achieve the continuity of the designated parts of the product High precision electroplating; this process has good electroplating quality stability and high accuracy, which can avoid the waste of gold plating cost of Tai Fook. Through the combination of molds, two-sided coatings with different specifications on multiple parts and surfaces can be obtained. The process determines the location of the gold plating based on the electroplating engineering drawings, and requires that the material has no deformation or distortion, otherwise it is easy to cause missing plating and abnormal electroplating areas, which will affect the quality stability. The groups of electroplated terminals suitable for connector stampings are as follows: Round 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. Through the combined use of multiple equipment, it can meet the needs of diversified gold-plating areas and thickness specifications. This process adjusts the gold-plating position or area according to the 'Electroplating Engineering DrawingThe groups of suitable electroplating materials for connector stamping parts are as follows: 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. The groups of suitable electroplating materials for connector stamping parts are as follows: Through the above process, the oxidation of the material products is reduced, the contact resistance is reduced, the soldering resistance is increased, the wear resistance is increased, the electrical conductivity of the circuit is directly improved, and the connector stamping is extended.
