Embodiment Construction
[0029] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0030] The material of the cover plate in the present invention is a composite material composed of polyvinyl chloride resin, industrial aluminum powder and processing aids, wherein the polyvinyl chloride resin adopts resin powder with a polymerization degree of 700, and the industrial aluminum powder selects pure aluminum above 100 mesh Powder (has been coupled), processing aids include stabilizers, lubricants, foam regulators, etc.
[0031] First, put 100kg of polyvinyl chloride 700 (or 800) resin powder, 20kg of metal powder, 8kg of stabilizer, 2kg of external lubricant, 2kg of internal lubricant, 8kg of foam regulator, 0.5kg of foaming agent, and 10kg of nucleating agent Put it into the high-speed mixer, start the high-speed mixer ...

Abstract
The invention relates to a recycling technology field of a covering plate for processing a circuit board, and especially relates to technologies for manufacturing and recovering a recoverable circuit board boring covering plate. Mixed particles prepared by a high-molecular polymer, a metal powder, an auxiliary agent and a foaming mother material, are manufactured to be a plate by a plastic plate production line, the plate is manufactured to be the covering plate by cutting and hot pressing through a hot press, the covering plate can be directly prepared to be recovery particles through cutting and particle cutting after boring the circuit board, the recovery particles and the foaming mother material are mixed to prepare the plate directly through the plastic plate production line, the plate can be prepared to be the covering plate by cutting and hot pressing through the hot press, and the cycle utilization may be repeated. Compared with the prior art, the technologies for manufacturing and recovering a recoverable circuit board boring covering plate not only reach technology requirement for the circuit board boring covering plate, but also implement the multi-time recovery utilization of the circuit board boring covering plate, reduce waste and pollution problems brought by a traditional covering plate, greatly save production cost, and protect environment.
Description
technical field [0001] The invention relates to the technical field of recycling cover plates for processing circuit boards, in particular to a manufacturing and recycling process of a recyclable circuit board drilling cover plate. Background technique [0002] Printed circuit board (PCB for short) is a substrate for assembling electronic parts. Its main function is to make various electronic parts form a predetermined circuit connection and play the role of relay transmission. It is the key electronic interconnection of electronic products. pieces. The interconnection of such electronic components requires drilling holes on the printed circuit board to complete the fixing and connection of the electronic components. [0003] When drilling a circuit board, due to the very high rotational speed of the drill bit, the drill bit itself has poor toughness, high brittleness, and is very expensive. In order to reduce the wear and tear of the drill bit, improve the drilling accura...
