Description
Technical field
The utility model relates to a kind of etching machine, specifically a kind of etching machine etching the uniformity for improving FPC.
Background technology
Flexible PCB (FPC) be make for base material with polyimides or polyester film a kind of there is the reliability of height and excellent flexual printed circuit board (PCB).It has the advantages that flexible structure, volume are little, lightweight, can meet dynamic flexible requirement, is therefore widely used in the fields such as space flight, military affairs, electronics.But along with short, little, thin, the light development trend of electronic product is more and more obvious, the density of FPC and fine degree are had higher requirement.Be embodied in: live width, line-spacing require more and more less, and the control range of live width tolerance is more and more narrow, adopt conventional end copper thickness and etching parameter to be difficult to meet 5mi l/5mi l (live width/line-spacing) etching requirement below.Find best etching condition, improving the etch effect on fine rule road and improve etch uniformity, by being the key point solving fine rule road etch issues, is also the emphasis point that FPC develops to high-end product.
Utility model content
The utility model in order to solve the problems of the technologies described above, provide that a kind of reasonable in design, structure is simple, etching evenly, etching machine that etch effect is good.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of etching machine etching the uniformity for improving FPC comprises structure for conveying, spray structure and fixed mount, spray structure is fixed on fixed mount, comprise liquid feed tube, snorkel, medicine liquid spray pipe, air jet pipe, liquid medicine sprayer and valve, medicine liquid spray pipe is connected with liquid feed tube, air jet pipe is connected with snorkel, medicine liquid spray pipe is provided with liquid medicine sprayer, air jet pipe is provided with valve, medicine liquid spray pipe and air jet pipe are spaced, described structure for conveying comprises roller bearing, roller bearing is fixed on fixed mount, and is positioned at the below of spray structure.The liquid of liquid medicine sprayer ejection acts on FPC, and after liquid contacts with FPC, blown off, this technique can prevent liquor residue from corroding circuit, prevents liquor residue simultaneously at once.
Further, described spray structure has one group at least, is positioned at the top of roller bearing.
Further, described liquid medicine sprayer and valve are demountable structure.
Etching machine of the present utility model compared with prior art, often arrange between nozzle at conventional etch machine, add an exhaust nozzle, after liquid is contacted with FPC, blown off at once, prevent liquor residue from corroding circuit, prevent liquor residue, etching solution and FPC are more prone to control time of contact on the one hand, and the working ability of etching machine is promoted simultaneously, processing line can be made more accurate, and etch effect is good; On the other hand, pressure uniform when etching solution and FPC are reacted is unified, and etching evenly.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
