Abstract
The invention discloses a PCB solder mask developing line. A water washing part of the PCB solder mask developing line is divided into three segments. An overflow method of enabling water in a back segment to be used for water in a front segment is employed in all the three segments. Each segment is provided with a tap water inlet and an overflow port. An ice water coil is arranged between two tap water inlets or between one tap water inlet and one overflow port. The ice water coil continuously provides ice water circularly. In the PCB solder mask developing line, the ice water is supplied continuously and circularly through the ice water coils so that water overflown from a back water washing groove in the water washing part to a front water washing groove in the water washing part is subjected to a cooling effect of the ice water coils, thereby greatly decreasing a water temperature.
Description
Technical field
The invention belongs to wiring board print field, relate in particular to a kind of PCB welding masking developing line.
Background technology
In the surperficial welding masking developing technique of printed-wiring board (PWB) (being PCB), PCB welding masking developing line in order to not have the ink of polymerization reaction take place to rinse out in the printed ink in PCB surface after exposure manufacture process, reserve through hole to be welded on pcb board and other PAD, all circuits and large copper face are covered with ink, and then the consumption of scolding tin and short circuit and the bridging causing while preventing wave-soldering while saving part in client.Developing line is comprised of develop section, washing section and drying section conventionally, in the section of developing, adopt liquid medicine (sodium carbonate liquor) under specified temp, the ink that photopolymerization reaction does not occur to be rinsed out, at washing section, residual liquid medicine and the ink residue of plate face washed, in drying section, the moisture of plate face is dried up.The after washing section water temperature over-high if development section is windowed, SMT, QFP etc. have every the place of weldering bridge has bridge disconnected, the risk coming off every line, half consent has the risk of oil spilling.What adopt at present is that (3 roads develop universe developing line, 17 road washings), its pumping adopts the mode of built-in cell body, because the pumping working time is longer, wiring board cause cell body fluid temperature to rise, so can cause the quality abnormals such as bridge is disconnected, oil spilling during through washing section after the section of developing.In order to reduce water temperature, original equipment provides a kind of heat sink of overflow at washing section, but this kind of mode not only has cooling-down effect not produce a desired effect, and also has water consumption very large, increases the deficiencies such as production cost.
Summary of the invention
The object of the present invention is to provide a kind of PCB welding masking developing line, the method cooling-down effect that is intended to solve existing reduction pumping cell body fluid temperature is not good, the problem that water consumption is large.
The present invention realizes like this, a kind of PCB welding masking developing line, washing section is divided into 3 sections, the overflow mode of using before water after all adopting, at every section, be all provided with tap water water inlet and overflow vent, medial launder at tap water entrance and tap water entrance or tap water entrance and overflow vent is provided with frozen water coil pipe, and frozen water coil pipe constantly circulation provides frozen water.
Further, described washing section is divided into 3 sections, be specially: the washing of first paragraph 1-6 road, the washing of second segment 7-11 road, the 3rd section of 12-17 road washing, the overflow mode of using before water after all adopting, has respectively the constantly fresh normal temperature tap water of input of a tap water entrance in the 3rd road, 6 roads, 11 roads, 14 roads, 17 roads, then every section of correspondence, last the 1st road, the 7th road, 12 road have an overflow vent together.
Further, the first paragraph 1-6 road washing of washing section, the totally 3rd road, two, the 6th road tap water water inlet, 3rd, the overflow line between 2 road washings is high compared with the overflow line between the 2nd, 1 road washing, equally, 6th, the overflow line between 5 road washings is high compared with the overflow line between the 5th, 4 road washings, and the overflow line height between the 4th, 3 road washings is between the 5th, 4 road washing overflow lines and the 3rd, 2 roads washing overflow line; The washing of second segment 7-11 road, one, 11 road of Gong water inlet, is reduced gradually by left-to-right overflow line; The 3rd section of 12-17 road washing, Gong 17 roads, two, 14 road water inlet, reduced gradually by left-to-right overflow line, in the 2nd road, the 5th road, the 9th road, 13 road, 16 road cell body, increases frozen water coil pipe, and frozen water coil pipe constantly circulation provides frozen water.
effect gathers
PCB welding masking developing line of the present invention, is constantly circulated frozen water is provided by frozen water coil pipe, and after washing section, the water of road rinsing bowl overflows in front road rinsing bowl process and can be subject to the cooling of frozen water coil pipe, and water temperature can significantly be reduced.To the half consent aperture oil spilling due to the higher easy generation of water temperature, have larger improvement every the weldering bridge anti-welding quality problem such as come off.
