Description
Technical field
The present invention relates to wiring board processing technique field, specifically a kind of LED lamp panel shaping process.
Background technique
With the continuous development of route board industry, wiring board for various purposes also occurs therewith, and production requires also increasingly smart
It is close, fine, it is particularly due to the backboard of large LED display screen, is that muti-piece wiring board is spliced, plate is interior without positioning through hole or logical
Bore dia is too small (1.0MM or less), and seamless spliced between wiring board is the key that LED display effect, traditional operation mode
It has been unable to satisfy this requirement, as wiring board producer, has researched and developed the new production method production effect that reduces that increased production cost
Rate, and the direction that the wiring board to meet the requirements of the customers is wiring board producer effort is manufactured out, while production process
Management also become the key point that yields products of quality.
The assist side design phase encounters, common practice too small (1.0mm or less) without location hole or through-hole diameter in plate
It is that design increases technique edges, satisfactory location hole is added on technique edges, is convenient for processing and forming, because of technique edges meeting after patch
There are two ways to removal, common removal technique edges:
1, design stamp hole connects wiring board main body with technique edges, after the completion of patch, breaks except technique edges；
2, designed lines plate main body is directly connect with technique edges, is cut V slot by V-CUT, after the completion of patch, is broken except technique
Side.
But both the above removes the design of technique edges, is only limitted to allow the client of technique edges shipment, and after technique edges removal
Edges of boards out-of-flatness directly affects the splicing between wiring board plate, if client does not allow plus technique edges, both the above design is equal
It cannot use.Therefore how to no location hole and route sheet metal forming and test position fix existing for technique edges to be not allow for as route
Plate producer's urgent problem to be solved, therefore those skilled in the art provide a kind of LED lamp panel shaping process, with
Solve the problems mentioned above in the background art.
