Abstract
The invention discloses water inlet structures of a passivated rinsing tank and a subordinate-liquid rinsing tank of a PCB. The passivated rinsing tank is arranged adjacent to the subordinate-liquid rinsing tank; a first water inlet is formed in the bottom of the passivated rinsing tank; a water inlet pipe is connected with the first water inlet of the passivated rinsing tank; an overflow port is formed in the upper part of the passivated rinsing tank; a second water inlet is formed in the lower part of the subordinate-liquid rinsing tank; and the overflow port of the passivated rinsing tank is connected with the second water inlet of the subordinate-liquid rinsing tank through an overflow pipe. According to the water inlet structures of the passivated rinsing tank and the subordinate-liquid rinsing tank of the PCB, the passivated rinsing tank and the subordinate-liquid rinsing tank are disconnected; water is pumped into the passivated rinsing tank; the liquid in the passivated rinsing tank overflows to the subordinate-liquid rinsing tank through the overflow pipe; the mutual circulation of the liquid in the passivated rinsing tank and the subordinate-liquid rinsing tank can be blocked, so as to avoid pollution of the liquid in the tanks and to ensure normal production.

Technical field
The invention belongs to field of printed circuit board fabrication, be specifically related to the water inlet modified node method of a kind of passivation after washing groove and sub-liquid after washing groove.
Background technology
In prior art, the passivation after washing groove of PCB is disposed adjacent with sub-liquid after washing groove, and when washing, the bottom of passivation after washing groove and sub-liquid after washing groove was interconnected by a communicating pipe, water inlet pipe passes into sub-liquid after washing groove, washing water is by mutually circulating in communicating pipe after passivation rinsing bowl and sub-liquid after washing groove, because passivation is acid, and sub-liquid is alkalescence, liquid in two rinsing bowls mutually circulates and understands chemically reactive and produce crystallization, thus cause water quality blackening, affect tank liquor, and of a specified duration easily cause line clogging, impact is normal produces.
Summary of the invention
In order to solve the problem, the invention provides the water inlet structure of a kind of PCB passivation after washing groove and sub-liquid after washing groove, the water inlet structure of this PCB passivation after washing groove and sub-liquid after washing groove can block the mutual circulation of liquid in passivation after washing groove and sub-liquid after washing groove, avoid flowing the tank liquor caused mutually to pollute, ensure normally to produce.
The present invention in order to the technical scheme solving its technical problem and adopt is:
The water inlet structure of a kind of PCB passivation after washing groove and sub-liquid after washing groove, passivation after washing groove is disposed adjacent with sub-liquid after washing groove, the bottom of described passivation after washing groove is provided with the first water inlet, water inlet pipe connects the first water inlet of described passivation after washing groove, the top of described passivation after washing groove is provided with overfall, the bottom of described sub-liquid after washing groove is provided with the second water inlet, and the overfall of described passivation after washing groove is communicated with by overflow pipe with between the second water inlet of described sub-liquid after washing groove.
The present invention in order to the further technical scheme solving its technical problem and adopt is:
Say further, the top of described passivation after washing groove is provided with the 3rd water inlet, and described water inlet pipe branches out water inlet pipe, and described water inlet pipe connects the 3rd water inlet of described passivation after washing groove.
Say further, the bottom of described passivation after washing groove is provided with the first sewage draining exit.Furthermore, described first sewage draining exit is provided with valve.
