Description

Large-size single-sided electroplating clamp

Technical Field

The utility model relates to the technical field of microelectronics, in particular to a large-size single-sided electroplating clamp.

Background

The electroplating is to plate a thin layer of other metals or alloys on the surface of some metals by utilizing the electrolysis, and the process of adhering a metal film on the surface of the metal or other material parts by utilizing the electrolysis is used for preventing oxidation (such as rust) of the metal, improving the wear resistance, conductivity, reflectivity, corrosion resistance (such as copper sulfate) and beautiful appearance, and the like. For example, in the fabrication of micro-wave circuit boards in the micro-assembly (MCM) process, a rogers copper-clad substrate is generally used, and copper metal materials oxidize to red during subsequent high-temperature operation, and gold plating treatment is required to be performed on the front surface before use, so as to reduce transmission loss and ensure bonding reliability. Because the two sides of the traditional microwave circuit board are provided with metals, if the two sides are not protected, the metals on the two sides are plated at the same time, so that waste is caused, and in order to avoid the gold embrittlement effect caused by direct welding of thick gold, a gold removal process is added in the subsequent operation; if current is applied only to the front side, the back side metal is consumed as an anode, and copper metal enters the plating solution to pollute the plating solution, so that the back side needs to be protected.

The traditional back surface protection adopts gluing protection, namely, a layer of protection glue is coated on the back surface of a substrate, and the protection glue is removed after electroplating is completed; this approach requires a longer process and higher costs for the glue application and exposure equipment. The single-sided electroplating is realized by using the protection of the mucous membrane, the process is relatively simple, the mucous membrane is stuck on the back surface of the circuit board, and the mucous membrane is removed after the electroplating is finished; however, the adhesive on the back metal is left by the adhesive film of the general adhesive tape, the adhesive is not easy to remove, and the hidden trouble is caused by the residual adhesive in the subsequent sintering process.

Patent document (issued publication number CN 205152380U) discloses a fixture for single-sided electroplating of a substrate, which uses the tension of water to make the back of the substrate firmly cling to the groove of the supporting plate, and the probe electrode plays the role of electrode electroplating and simultaneously plays the role of compacting the substrate, so that the back of the substrate is completely isolated from the electroplating solution, and the single-sided electroplating of the substrate is successfully realized.

However, in the use process of the fixture, if the substrate with a larger size needs to be subjected to electroplating treatment, the size of the substrate may be matched with the size of the groove, the substrate can be just placed on the groove, when the substrate needs to be taken after electroplating is completed, a worker cannot take the substrate, the substrate groove needs to be lifted up and taken from the groove by using a tool, or the fixture is turned over to pour the substrate out of the groove, and the operation is troublesome and inconvenient.
