Hybrid PCB for microwave RF

Hybrid PCB is usually used in microwave RF series products

With the rapid development of electronic communication technology, in order to achieve high-speed, high fidelity signal transmission, more and more microwave RF PCB are used in communication equipment. The dielectric materials used in high frequency hybrid circuit board have excellent electrical properties and good chemical stability, which are mainly shown in the following four aspects.


1. Hybird PCB has the characteristics of small signal transmission loss, short transmission delay time and small signal transmission distortion.

2. Excellent dielectric properties (mainly refers to: low relative dielectric constant DK, low dielectric loss factor DF). In addition, the dielectric properties (DK, DF) remain stable under the environmental changes of frequency, humidity and temperature.

3. High precision characteristic impedance control.

4. Hybird PCB has excellent heat resistance (TG), processability and adaptability.

Microwave high frequency hybrid PCB is widely used in wireless antenna, base station receiving antenna, power amplifier,  radar system, navigation system and other communication equipment.


Based on one or more factors of cost saving, improving bending strength and electromagnetic interference control, high-frequency semi cured sheet with low resin fluidity and FR-4 substrate with smooth medium surface must be used in the laminated design of high-frequency composite laminate. In this case, there is a great risk for the bonding control of products in the pressing process.

1. A kind of high frequency hybrid PCB controlled depth composite laminate structure, the high frequency hybrid PCB includes L1 copper layer( high-frequency sheet), L2 copper layer( PP sheet), L3 copper layer( epoxy resin substrate) and L4 copper layer in turn; slot holes with the same size are arranged at the same position on the L2 ,L3 and L4 copper layer; the L4 copper layer is arranged from the inside Three in one buffer material, steel plate and kraft paper are stacked successively from outside to outside; aluminum sheet, steel plate and kraft paper are successively stacked on L1 copper layer from inside to outside.
2. According to 1st feature,the three in one buffer material is a buffer material sandwiched between two release membranes.

3. According to 1st feature,the laminated structure of the high-frequency plate controlled deep mixing plate is characterized in that the high-frequency sheet material is a polytetrafluoroethylene substrate.

The expansion and shrinkage characteristics of the high frequency hybrid PCB composite  laminate are different from those of the ordinary epoxy resin  substrate, so it is difficult to control the plate curvature and  shrinkage, and the processing method of slotting first and then pressing will cause the problem of sheet metal depression. Three in one buffer  material is set on one side of the groove, and the buffer material can  be filled into the slot hole during pressing, so as to avoid the  depression problem. Kraft paper is set on both sides of the board to  cushion the pressure and balance Uniform heat transfer, set steel plate to ensure uniform heat  conduction in pressing, make the pressing flat, make the heat and  pressure balance during pressing, so as to better control the board curvature and expansion and contraction.
