Description
Technical field
The present invention relates to planer-type electroplating technology in PCB production procedures, and in particular to a kind of winged palladium anticorrosion extends
Service life guard method.
Background technology
, it is necessary to using stainless steel fixture is fixed on copper bar in PCB planer-types electroplate manufacturing process, fixture clamps plank and is in
An existing whole piece, enter oil removing → bis- washing → microetches → bis- washing → pickling → copper facing from pre-treatment upper plate successively according to plating flow
→ high-order washing → pickling → tin plating → bis- washing → lower plate turns the flow production of etching → nitre extension → bis- washing → upper plates, in life
Produce in flow, copper bar flies palladium and is required for by circular flow on the nitric acid groove containing more than 10% sulfuric acid and more than 40%, raw
Production plank on strong acid be unable to drip-dry in the short time, have residual drip on the rhombus stainless steel frame at the top of winged palladium, decoction along
Smooth steelframe is fallen on copper bar, through chemical reaction after a while, make copper bar occur it is different degrees of sting erosion, cause fixture
Gap between copper bar is in contact with it out-of-flatness, loosens, and causes loose contact, and the CURRENT DISTRIBUTION on fixture is uneven,
Cause electro-coppering thickness ununiformity even, copper is thick insufficient or partially thick, causes client to complain indemnity or even loses the weighty responsibility of order, copper
The corrosion of row causes the increase of investment of production cost, causes productive profit to reduce.At present, in this respect without improvement side well
Case, spend less investing to reduce the corrosion of copper bar, and extend its service life.
The content of the invention
Less investment is spent to reduce the corrosion that copper flies palladium the technical problem to be solved by the invention is to provide a kind of,
Extend the service life that copper flies palladium, the winged palladium anticorrosion for reducing customer complaint risk increases the service life guard method.
The technical solution adopted for the present invention to solve the technical problems is：A kind of winged palladium anticorrosion increases the service life protection
Method, on the basis of existing winged palladium, the top of winged palladium, the door curtain are fixed on using door curtain anti-corrosion rubber or PVC board, PP plates
Reverse V-shaped mode is presented in anti-corrosion rubber or PVC board, the width design of PP plates, can cover entirely at the top of winged palladium, length is with flying
The length of palladium is consistent.
Further, first of washing design after copper facing (stripping and hanging) comes out is defined by not being dipped into copper bar；Second after stripping and hanging
Washing is washed using top spray, and the acid for making to remain in rubber or PVC board, PP plates is rinsed well, prevents that being brought into coating bath pollutes.
Further, the door curtain anti-corrosion rubber or PVC board, PP plates stretch out 2- than the rhombus stainless steel edge at the top of winged palladium
4cm, prevent liquid medicine from flowing on winged palladium.PVC board, PP plates increase intensity using hot briquetting mode, while needed PVC board, PP
Plate is fixed on above rhombus stainless steel.
Further, the PVC board or PP plates are provided with right angle PVC board or PP plates, the right angle PVC board every 80-100cm
Or one side of PP plates and PVC board or PP intralamellar part sweat solderings, another side is fixed by stainless steel screw and rhombus stainless steel to be connected
Connect.
Further, the right angle PVC board or the length and width of PP plates are 3cm, thickness 2-3mm.
The present invention has advantages below：The highly acid liquid medicine drop of the incomplete drip-dry in palladium circular flow is flown can effectively be protected
Fall on copper bar, cause copper bar to corrode；The service life of winged palladium can be extended, reduce equipment because service life shortens, increase is set
The input of standby cost, while reduce maintenance man-hours waste, the time that can have abundance to other equipment maintains, it is ensured that sets
Standby is stable, the service life of extension device, preferably ensures production quality.
Brief description of the drawings
Fig. 1 is the structural representation of PVC board used in the embodiment of the present invention；
Fig. 2 is the scheme of installation of PVC board used in the embodiment of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
Embodiment
A kind of winged palladium anticorrosion increases the service life guard method, on the basis of existing winged palladium, is fixed using PVC board 1
Flying the top of palladium, reverse V-shaped mode is presented in the width design of the PVC board 1, can cover entirely at the top of winged palladium, length
It is consistent with the length of winged palladium, as depicted in figs. 1 and 2.
In the present embodiment, first of washing design after copper facing (stripping and hanging) comes out is defined by not being dipped into copper bar；After stripping and hanging
Two washings are washed using top spray, and the acid for making to remain in PVC board is rinsed well, prevents that being brought into coating bath pollutes.
In the present embodiment, the PVC board 1 stretches out 3cm than the edge of rhombus stainless steel 2 at the top of winged palladium, prevents liquid medicine from flowing to
Fly on palladium.PVC board 1 increases intensity using hot briquetting mode, while needs PVC board 1 being fixed on above rhombus stainless steel 2.
In the present embodiment, in order to prevent coming off because flying palladium vibrations, increase its firm performance, right angle is installed every 100cm
PVC board 3, one side and the inside sweat soldering of PVC board 1 of the right angle PVC board 3, another side by stainless steel screw and rhombus not
Rust steel 2 is fixedly connected.The length and width of the right angle PVC board 3 are 3cm, thickness 2mm.
In the present embodiment, the PVC board 1 or door curtain anti-corrosion rubber or PP plates etc..
The present invention can effectively protect the highly acid liquid medicine of the incomplete drip-dry in palladium circular flow is flown to drop onto on copper bar, make
Corrode into copper bar；The service life of winged palladium can be extended, equipment is reduced because service life shortens, increase the input of equipment cost,
Simultaneously reduce maintenance man-hours waste, can have to other equipment abundance time maintain, it is ensured that equipment it is stable,
The service life of extension device, preferably ensures production quality.
