The existing mechanical drilling method is: A. The drilling process of the double-sided board is: after the backing plate, copper clad laminate, and aluminum sheet are assembled, insert the PIN nail, use the air clamp to clamp the PIN to drill the hole, and the PIN must be inserted after the drilling is completed. Nail removal; B. The drilling process of the multi-layer board is: after the shutdown, the backing plate, copper clad laminate, and aluminum sheet are assembled and then the aluminum sheet is pasted on the production board with masking tape. The shutdown will cause a waste of time and improve efficiency. reduce

Embodiment Construction
[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.
[0016] Such as Figures 1 to 2 The method of this pinless positioning adhesive drilling of the present invention shown, it comprises the following steps:
[0017] a. Substrate preliminary processing 7: select the substrate, and then make the substrate into a multi-layer board without drilling through cutting, inner layer etching and pressing processes, or make it into a multi-layer board with positioning holes through cutting and positioning drilling of double panels. Make positioning holes through the target hole of the multi-layer board or the edge of the double-sided board, as the fixing hole when the drilling machine drills.
[0018] b. Measurement 8: Use the measuring positioning ruler to measure the hole distance of the positioning holes of the above-mentioned multilay...

The invention discloses a pin-free positioning, rubberizing and drilling method which comprises the following steps of a, selecting a base board, fabricating the base board into an undrilled multi-layer board by cutting, inner layer etching and laminating technologies or fabricating the base board into a double-sided board with positioning holes by cutting, positioning and drilling technologies; b, measuring distances of the positioning holes of the multi-layer board by a measuring and positioning ruler and placing the multi-layer board on the measuring and positioning ruler; c, sequentially stacking an aluminum sheet, a copper-clad board and a backing board on the measuring and positioning ruler, completing assembling of a circuit board, performing rubberizing on the four sides by a rubberizing machine, performing fabrication into a sleeve board, taking down the measuring and positioning ruler, and gently carrying the sleeve board to a waiting drilling area of a drilling machine; and d, aligning the whole sleeve board to positioning pins for compaction and fixing during board production, and taking down the whole sleeve board from a table top of the drilling machine after processing completion. With the adoption of the scheme, a processing technology procedure is reduced; the labor intensity is reduced; the production efficiency is improved; and a popularization significance is great.
Description
technical field [0001] The invention belongs to the technical field of printed circuit board manufacturing, and in particular relates to a method for positioning, pasting glue and drilling a circuit board without pins. Background technique [0002] Circuit boards are an essential part of all types of electronic products today. With the continuous development of electronic information technology, the demand for circuit boards continues to increase, and the speed of replacement is significantly accelerated.
