Problems solved by technology

[0004] The problem that the existing CNC mechanical drilling machine cannot process large-size boards due to the size of the drilling machine table
At present, the processing size of ordinary drilling rigs is generally W21.5″*L27″, and the largest processing size is W27″*L32″, but it is difficult for ordinary drilling rigs to solve the large size of W (MAX27″)*L (27″-43″). Drilling of circuit boards

Embodiment Construction

[0024] The present invention will be further elaborated below in combination with specific embodiments.

[0025] Segmented positioning cross-axis operation, in the engineering design, first design three point holes within 10.5" on the left and right sides of the middle, divide the main drilling program into two programs according to the centerline position, and use the first drilled holes respectively The positioning hole is positioned and drilled twice.

[0026] A method for drilling a large-sized circuit board, the steps of the method are as follows:

[0027] a. Pinning: Place the circuit board in the pin machine, use the pin machine to punch the pin for positioning in the middle of the long side of the circuit board;

[0028] b. Set the board: place the circuit board with the pins in step a on the shaft table of the drilling machine. The drilling machine includes six drilling shafts, and the drilling shafts are the first drilling shaft, the second drilling shaft, the third...

Abstract

A drilling machining method for a large-size circuit board includes the following steps of mounting of dowels, placing of the board, drilling of locating holes, drilling, drawing out of the dowels, start of drilling, drawing out of the dowels and completing of drilling. By the adoption of the drilling machining method for the large-size circuit board, the problem that the large-size circuit board cannot be manufactured due to the size limit of a table board of a common drilling machine is solved, and by the adoption of the technical application, drilling machining of the large-size circuit board (W(MAX27'')*L(27''-43'')) can be achieved through the common drilling machine.

Description

technical field [0001] The invention relates to the field of circuit boards, in particular to a method for drilling large-sized circuit boards. Background technique [0002] The circuit board drilling methods mainly include: [0003] Die punching, mainly used in the field of single panel; 2. CNC mechanical drilling machine drilling, the most widely used, mainly used for through-hole drilling of double-sided or multi-layer circuit boards; 3. Laser drilling, mainly used in Blind hole processing. [0004] The existing CNC mechanical drilling machine cannot process large-size boards due to the size of the drilling machine table. At present, the processing size of ordinary drilling rigs is generally W21.5″*L27″, and the largest processing size is W27″*L32″, but it is difficult for ordinary drilling rigs to solve the large size of W (MAX27″)*L (27″-43″). Drilling of circuit boards. Contents of the invention [0005] The technical problem mainly solved by the present inventio...
