Abstract

The invention provides a drilling and cooling method for a circuit board. The drilling and cooling method can reduce processing temperature and prevent various problems existing during liquid cooling,so problems of processing retention and processing lamination can be avoided, and built-up edges and processing bur production can be reduced. Therefore, machine processing performance of a PTFE circuit board can be greatly improved. the equipment used in the method is economic and simple and easy to realize; cold air in the method is compression air, so advantageous of economic benefits and environment protection, damage prevention to sheet material and low cost can be achieved; and the drilling and cooling method for the circuit board can be applied to the field of PTFE circuit board processing.

Description

technical field [0001] The invention relates to a drilling cooling method of a circuit board, in particular to an innovative technology of a drilling cooling method of a PTFE circuit board. Background technique [0002] Due to its excellent dielectric properties (currently the lowest loss among substrates), PTFE circuit boards can be applied to high-frequency and high-speed transmissions with a transmission rate of 100GHz and above. The transmission loss of PTFE circuit board is closely related to its processing quality. [0003] During the machining process of PTFE circuit boards, due to the soft material of PTFE, which is a difficult-to-break chip material, the phenomenon of chip entanglement on drill pins / milling cutters is serious (patents can cover drilling and milling), and large burrs are prone to appear, which affects processing The quality also affects the loss of the signal transmission of the end product. [0004] At present, the main solutions to such problems ...
