Embodiment Construction

[0022] The present invention will now be described in further detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0023] Such as Figure 1 to Figure 5 As shown, a tooling for the PTH production process of a thin plate includes a hanging basket 1 and a frame piece 2, the hanging basket 1 has a card slot 3, and a thin plate 4 is fixed and compressed inside the frame piece 2, and the frame piece 2 Insert it vertically into the card slot 3 of the hanging basket.

[0024] Such as Figure 4 As shown, the hanging basket 1 is a hexahedral square frame structure made of stainless steel, and at least two sides of the hanging basket 1 are provided with slots 3 for fixing the frame pieces; the slots 3 are sawtooth-shaped, and the teeth The spaci...

Abstract

The invention relates to a plated through hole (PTH) manufacturing technique tool of a sheet. The tool consists of a hanging basket and a frame sheet, wherein the hanging basket is provided with a clamping groove, a sheet is fixed and tightly-pressed inside the frame sheet and the frame sheet is inserted vertically into the clamping groove. With the adoption of the PTH manufacturing technique tool of the sheet, not only is the concept that the PTH manufacturing technique can not be used for processing the sheet is changed, and the bad puckering of the products made through the PTH manufacturing technique is effectively reduced, but also the unavoidable problem of 'hanging basket prints' of the tradition PTH manufacturing technique is solved completely.

Description

technical field [0001] The invention relates to equipment used in the production process of printed circuit boards, in particular to a tooling for the PTH production process of thin plates. Background technique [0002] PTH (Plated Through Hole) is the meaning of plated through hole, the function is to plate the original non-metallic hole wall with a thin layer of copper (ie metallization), so as to facilitate the smooth plating of subsequent electroplating copper, so that the upper and lower copper layers Or achieve the purpose of connecting with the inner layer copper smoothly. This process is completed through the chemical reaction of the chemical solution, so the product is carried out in the bath with shaking and air blowing during the whole operation process. [0003] When the traditional PTH process is in operation, it uses a stainless steel hanging cage to place the product, and then performs soaking and turnover operations in each medicine tank on the PTH productio...
