Technical Field
The invention relates to the field of circuit boards, in particular to a composite filtering device for a copper-deposited wire gumming slag removal groove.
Background
In the processing process of the PCB (Printed Circuit Board ) multilayer board, when the multilayer board passes through drilling, the mechanical drill bit runs at high speed, and high temperature about 200 ℃ is generated to burn and coat resin on the periphery of the hole wall, so that the conduction of inner copper and electroplated copper is affected. In order to solve the problem of residual resin glue in holes after drilling, a glue residue removing groove is arranged on the copper-deposited wire, so that the residual glue in the holes can be removed, the copper surface of the inner layer is cleaned, and the electroplated copper and the inner layer copper can form good combination. Most of the current glue residue removing grooves of copper deposited wires break loose polymer bonding at 65-75 ℃ by using alkaline potassium permanganate, so that the polymer is peeled off from the hole wall, and the aim of cleaning inner copper is fulfilled. As byproducts such as MnO2, plate dust, and in-hole glue slag are generated in the chemical reaction in the process, the filtering device is easily blocked, the temperature of a filter element of a filtering pump used for the filtering device is too high during mass production, and the operation is extremely difficult due to the too high temperature when the filter element of the filtering pump is replaced after the blocking. The existing glue residue removing tank of the copper sedimentation wire is not provided with a filtering system, only provided with a circulating system or an inflating system, and only a few devices provided with the filtering system can only filter out impurities with larger particles, the filtering effect is generally poor, and the product quality is also affected; and frequent pouring is required to remove more solid impurities such as byproducts, thus taking up much production time for maintenance.
