Problems solved by technology

[0010] 1. The existing electroplating protective adhesive has a slow curing speed and needs to go through a long heating and curing channel, and the degumming time is too long, and the entire curing time needs at least 30 seconds, which has become a technical bottleneck that limits the electroplating productivity;
[0011] 2. The existing electroplating protective glue takes a long time to remove. After electroplating, it takes at least 30 seconds to remove the remaining electroplating protective glue on the workpiece with an alkaline solution, which has also become a technical bottleneck that limits the electroplating productivity;
[0012] 3. The existing electroplating protective glue has poor corrosion resistance, and can only withstand 1 minute in the electroplating solution at 60 ° C. If the time of immersion in the electroplating solution exceeds 1 minute, the electroplating protective glue on the workpiece will fall off from the workpiece , loss of protection

Abstract

The invention discloses an electroplating protection glue, comprising 1-70 wt.% of phenolic resin and 30-99 wt.% of a solvent. In various embodiments of the present invention, the electroplating protection glue consumes a short time of 4-12 s for heating and curing, so as to greatly improve the production efficiency of the selective electroplating.

Description

technical field [0001] The invention relates to an electroplating protective glue and a method for electroplating a workpiece. Background technique [0002] Plating protective glue is a kind of resist that can resist the corrosion of electroplating solution. Before electroplating, the electroplating protection glue is covered on the area of ​​the workpiece to be electroplated (for example, a circuit substrate, an electrical contact terminal or other electrical products requiring electroplating) that does not require electroplating. During electroplating, the electroplating protective glue can protect the area of ​​the workpiece that does not require electroplating. After electroplating, these electroplating protective glues need to be removed from the workpiece. [0003] Since noble metals, such as gold, silver, etc., have good electrical conductivity and low resistance, they are often electroplated on workpieces to achieve good electrical connections. However, the high c...
