Description

A kind of FPC positions printing screen plate

Technical field

The utility model is related to print field, particularly a kind of FPC positioning printing screen plate.

Background technology

FPC circuit boards are referred to as flexible PCB, using more and more extensive.Used as LED lamp tube and LED lamplight setting FPC circuit boards, many light emitting diodes (LED lamp bead) and resistive element are mounted on FPC circuit boards, then be connected with power supply Come.When the single sided board of ultra-thin (below 0.025mm thickness) is produced, single sided board can be the FPC circuit boards of copper foil material, can make It is bad into many gauffers.

A kind of CNC gong plate producing process without NPTH holes positioning disclosed in patent document CN102510667 A, for printing In the production of the single PCS shipment in wiring board manufacturing process, when being molded for the first time in A, printed wiring board manufacturing process, whole Multiple list PCS plates are set on working plate, from directly adding hole to position on the spaced position between adjacent two PCS, and in each PCS Gong goes out portion profile after the connection position of upper reserved specified area, by the direct gong of whole working plate into predetermined overall figure, and Whole working plate is cut into multiple list PCS plates；When B, second shaping carry out CNC gong plates to single PCS plates, from being distributed in list At least 4 groove angles of the NPTH grooves on PCS plates carry out gong plate as shaping location hole, and gong falls the remaining reserved given side Long-pending connection position.The patent at least selects 4 NPTH groove angles in PCS to position, and PIN holes are placed on the position tangent with groove angle, and PIN Hole will as far as possible be distributed in four sides of PCS plates, with ensure PCS on four direction without movement, but the patent cannot overcome positioning to mark Know easily covered problem.

A kind of direct solidification realizes that the method for high accuracy silk-screen includes following step disclosed in patent document CN103619127 A Suddenly：A. chosen for the point for aligning as mark point on the wiring board for intending carrying out silk-screen；B. heat fixed type ink is selected, net is adjusted Within ± 3/ ten thousand, then the harmomegathus value of the piece film, make the deviation between the harmomegathus value of the mesh sheet film and the harmomegathus value of wiring board By in the silk-screen pattern transfer of the mesh sheet film to silk-screen half tone；C. silk-screen half tone contraposition is carried out using CCD para-position screen printer, is passed through CCD camera lenses recognize the mark point, and control silk-screen half tone to move by the control centre of CCD para-position screen printer to be positioned； D.CCD aligns screen printer silk-screen figure to wiring board, by the silk-screen figure solidification on wiring board.The patent positional precision is reachable Within ± 0.1mm, but the patent needs repeatedly to choose mark point and cannot overcome the easily covered problem of positioning mark.

Disclosed above- mentioned information is used only for understanding of the enhancing to the utility model background in the background section, therefore The information of prior art known to a person of ordinary skill in the art in not constituting home may be included.
