Satellite receivers, base station antennas, microwave transmission, car phones, global positioning systems, satellite communications, communication equipment connectors, receivers, signal oscillators, home appliance networks, high-speed computing computers, oscilloscopes, IC test instruments, etc., high-frequency communications. Intermediate frequency communications, high-speed transmission, high confidentiality, high transmission quality, high storage capacity processing and other communication and computer fields require high-frequency microwave printed circuit boards.
1. A high-frequency hybrid PCB controllable depth composite lamination structure, the high-frequency hybrid PCB includes L1 copper layer (high-frequency sheet), L2 copper layer (PP sheet), L3 copper layer (epoxy resin substrate), L4 copper layer in sequence; L2, L3, L4 copper layers are provided with slots of the same size at the same position; L4 copper layer is arranged with three-in-one buffer material from the inside to the outside, and steel plates and kraft paper are stacked from the outside to the outside; Aluminum plates, steel plates, and kraft paper are stacked on the L1 copper layer from the inside to the outside.
2. According to the first feature, the three-in-one buffer material is a buffer material sandwiched between two layers of release film.
3. According to the first feature, the laminated structure of the high-frequency board controlled depth mixed board of the present invention is characterized in that the high-frequency sheet is a polytetrafluoroethylene sheet.
The expansion and contraction characteristics of the high-frequency hybrid PCB composite board are different from those of the ordinary epoxy resin substrate, so the warping and shrinkage of the board are difficult to control, and the processing method of first grooving and then pressing will cause the board problem metal dents. The three-in-one buffer material is set on one side of the groove, and the buffer material can be filled into the groove hole during pressing to avoid the problem of dents. Kraft paper buffer pressure is set on both sides of the cardboard to balance the heat transfer uniformly, and the steel plate is set to ensure uniform heat conduction during pressing, so that the pressing is flat, and the heat and pressure during the pressing process are balanced, so as to better control the curvature and expansion of the board.
