The emergence of black holeized direct electroplating is a challenge to traditional PTH. Its biggest feature is to replace the traditional electroless copper plating process. The conductive film formed by physical action can be directly transferred to electroplating. From an efficiency point of view, due to the simplified process procedures and reduced control factors, compared with traditional PTH manufacturing procedures, the number of drugs used is reduced, and the production cycle is greatly shortened. Therefore, the production efficiency is greatly improved, and the sewage treatment cost is reduced. The total cost of printed circuit board manufacturing is reduced.

The black hole process is an important step in the fpc production process, so what exactly is the black hole production line process?

Black holeization direct electroplating technology is a new process that replaces electroless copper plating. It uses a black solution composed of fine carbon black or graphite with strong conductivity, collectively referred to as black hole liquid, and the English name Blackhole. Its characteristics are to simplify the process of metallized holes, save man-hours, reduce material consumption, and effectively control the discharge of waste water with high stability.

The process flow is: whole-hole cleaner-twice black hole treatment-micro-etching-thermal curing-and anti-oxidation and other important processes.

The process and principle are explained as follows:

Black hole cleaning treatment-rinsing-first black hole formation tank-drying-rinsing-black hole adjustment treatment-rinsing-second black hole formation tank-heating and drying-micro-etching-rinsing-antioxidant treatment-rinsing-drying

1. Problem: Too much foam in the whole-cell cleaner

Reason:

(1) Too much bath liquid is brought out

(2) Insufficient washing

(3) The bath concentration is too high

Solution:

(1)A. For vertical production lines, the washing time should be increased

B. For horizontal production lines, the speed should be reduced.

(2) Check whether the washing water flows into the washing tank, and at the same time increase the water flow, and increase the washing time and temperature according to the process requirements.

(3) Check whether the preparation is carried out in accordance with the process requirements.

2. Problem: The turbidity of the whole-hole cleaner bath appears

Reason:

(1) The bath temperature is too high

(2) Many pore cleaners cannot complex with calcium ions in hard water

Solution:

(1) Check whether the bath temperature is within the process range.

(2) Use deionized water to prepare the tank solution and subsequent replenishment.
