Technical Field

The invention relates to the technical field of printed circuit boards, in particular to a PCB golden finger rubberizing device and a rubberizing method.

Background

In the production and manufacturing process of a Printed Circuit Board (PCB), after electrical testing of the PCB, a high temperature adhesive tape must be adhered to the PCB with a gold finger during the processing process to protect the gold finger, so as to prevent the gold finger from being damaged by oxidation or scratching.

At present, a high-temperature adhesive tape is generally pasted on a golden finger part of a PCB by a pure manual adhesive tape or a pasting machine. The pure manual rubberizing speed is slow, pastes partially easily and produces pincher trees, rubberizing inefficiency, pastes the precision not high, and manual pasting can leave fingerprint, sweat stain in the face easily simultaneously, causes the PCB board to be oxidized to influence the yield of PCB board, still appears the consequences such as scratch face very easily simultaneously. Although the problem of manual rubberizing can be avoided to the rubberizing machine rubberizing area, the rubberizing needs the rubberizing machine of difference to carry out the rubberizing of the model of different PCB boards, and the rubberizing is with high costs, is not suitable for batch rubberizing.
