Embodiment 1

[0022] A method for controlling the depth of a copper block on a buried copper plate, comprising the steps of:

[0023] Depth control slot gong belt design: use a flat end milling cutter to mill the slot, set the cutting point at the center of the slot, and use a back-shaped cutting tool;

[0024] Milling the surface of the horizontal table: Before milling the groove, fix a backing plate on the production platform, and then carry out controlled deep milling on the backing plate, wherein the depth of controlled deep milling is smaller than the thickness of the backing plate, so as to eliminate the height difference of the table;

[0025] Groove milling: Groove milling is carried out in the manner of roughing first and then finishing.

Embodiment 2

[0027] A method for controlling the depth of a copper block on a buried copper plate, comprising the steps of:

[0028] Design of deep-controlled groove gong belt: use flat end milling cutter to mill the groove, set the cutting point at the center of the groove, adopt back-shaped cutting tool, when cutting, the overlapping degree between the milling cutter and the milling cutter is 40% of the diameter of the cutter ±5%;

[0029] Milling the surface of the horizontal table: Before milling the groove, fix a backing plate on the production platform, and then carry out controlled deep milling on the backing plate, wherein the depth of controlled deep milling is smaller than the thickness of the backing plate, so as to eliminate the height difference of the table;

[0030] Groove milling: Groove milling is carried out in the manner of roughing first and then finishing.

Embodiment 3

[0032] A method for controlling the depth of a copper block on a buried copper plate, comprising the steps of:

[0033] Depth control slot gong belt design: use a flat end milling cutter to mill the slot, set the cutting point at the center of the slot, and use a back-shaped cutting tool;

[0034] Milling the surface of the horizontal platform: Before milling the groove, fix a 2.0mm backing plate on the production platform, and then carry out 1.0mm controlled depth milling on the backing plate;

[0035] Groove milling: Groove milling is carried out in the manner of roughing first and then finishing.

Abstract

The invention relates to a depth control method for a copper block of a buried copper plate. The depth control method comprises the following steps of designing a depth control groove milling tape; performing groove milling by a flat-end milling cutter, wherein a cutting point is arranged in the center of a groove, and hollow square feeding is employed; milling a horizontal tabletop, in which a cushion plate is fixed on a production platform before groove milling, depth control milling is performed on the cushion plate, the milling control depth is smaller than the thickness of the cushion plate to eliminate height difference of the tabletop; and performing groove milling, in which groove milling is performed by a mode of rough milling and fine milling. The effects of bottom smoothness andno peak are achieved by design optimization of the milling tape and by the mode of rough milling and fine milling under the condition that depth control equipment is not introduced.

Description

technical field [0001] The invention relates to the field of circuit boards, in particular to a method for controlling the depth of buried copper boards and copper blocks. Background technique [0002] With the multi-functional development of electronic products, the application of embedding copper block PCB is more and more extensive, the demand of customers is increasing, and the requirements for copper block are also increasing, but the existing deep control machine is expensive, The frequency of use is low, and the purchase of the depth control gong for the production of a small amount of embedded copper block PCB will increase the production cost of embedded copper block PCB. [0003] Without introducing depth control equipment, the present invention optimizes the design of the gong belt and adopts the method of thick gong + fine gong to achieve the effect of flat bottom and no edge. Contents of the invention [0004] Based on this, it is necessary to provide a metho...
