PCB News - Reasons for choosing high frequency circuit boards

High frequency circuit board is a special circuit board with high electromagnetic frequency. Generally speaking, high frequency can be defined as frequency above 1GHz.Its physical performance, accuracy and technical parameters are very high, and it is often used in automobile anti-collision system, satellite system, radio system and other fields. The high-frequency circuit board comprises a core board provided with a hollow groove and a copper-clad board bonded to the upper and lower surface of the core board through flow adhesive. The upper and lower opening edges of the hollow groove are provided with a guard edge.

The utility model provides the high frequency circuit board, the hollow core board slot opening and the opening on the edge of the guard has to stop the flow gel, in this way, the core board and on the adhesion of the surface and the lower surface of the copper clad laminates won't flow glue into the hollow grooves in the adhesive bonding can complete operation in a short period of time, the existing technology subject to secondary pressure to achieve high frequency circuit boards, high frequency circuit board of the utility model structure is simple, low cost, easy to manufacture.
