Problems solved by technology

When this kind of laser drilling machine is used to make soft boards, it will have the following disadvantages: (1) Due to the large diameter of the through hole, the base material of the soft board is prone to depression at the through hole, resulting in uneven board surface, resulting in subsequent drilling The hole diameters are different; (2) The distance between two adjacent through holes is too large. When the edge of the flexible board substrate is not located at the through hole, it will warp and cannot be attached to the bearing surface of the workbench, resulting in insufficient holding efficiency. (3) The size of the bearing surface of the workbench is relatively large, while the size of the base material of the flexible board is small, resulting in a low utilization rate of the bearing surface of the workbench, and the general area not covered by the base material of the flexible board Because the hole is connected with the outside world, the airtightness of the holding device is not good, which reduces the adsorption force of the workbench and affects the holding effect

Embodiment Construction

[0013] The flexible board holding device of the technical solution will be described in detail below in conjunction with the accompanying drawings.

[0014] Please also refer to figure 1 and figure 2 The flexible board holding device 100 provided in the first embodiment of the technical solution includes a first carrying device 110 , a second carrying device 120 and an air suction device 130 .

[0015] The first carrying device 110 includes a first carrying portion 111 , a first side wall 112 and a first bottom wall 113 .

[0016] The first bearing portion 111 is opposite to and parallel to the first bottom wall 113 . The first side wall 112 is disposed between the first bearing portion 111 and the first bottom wall 113 , and forms a rectangular parallelepiped structure together with the first bearing portion 111 and the first bottom wall 113 , thereby forming a first cavity 114 . In order to ensure airtightness, preferably, the first bearing portion 111 , the first side w...

Abstract

The invention relate to a soft board fixing device. The soft board fixing device comprises an air suction device and a first load bearing device communicated with the air suction device. The first load bearing device has a first cavity inside and comprises a first load bearing part. The first load bearing part is provided with a plurality of first through holes which are communicated with the first cavity. The soft board fixing device also comprises at least one second load bearing device. The at least one second load bearing device is arranged on the first load bearing part and has a second load bearing part. The second load bearing part is provided with a plurality of second through holes. The second through holes are communicated with the first through holes. The dimension of the second through holes is smaller than that of the first through holes. When used, the soft board fixing device can achieve better fixing effect and improve the excellent rate of subsequent products.

Description

technical field [0001] The invention relates to the technical field of soft board production, in particular to a soft board holding device. Background technique [0002] With the emergence of high-density interconnection (High Density Interconnection, HDI) flexible board demand, it is imperative to introduce the laser drilling process into the production of flexible boards. See literature: Kestenbaum, A.; D'Amico, J.F.; Blumenstock, B.J.; DeAngelo, M.A. et al. Published in Components, Hybrids, and Manufacturing Technology IEEE Transactions, Vol. 13, Vol. 4, pp. 1055-1062: Laser drilling of microvias inepoxy-glass printed circuit boards. At present, the flexible board drilling technology in the industry is not yet mature, and most of the existing laser drilling machines are designed for rigid boards. Since the size of the soft board is usually smaller than that of the hard board, and it has excellent flexural properties, it is easy to bend and deform under the action of ext...
