The definition of high frequency microwave PCB

High Frequency microwave PCB board refers to the special electromagnetic frequency circuit board, used in high frequency (greater than 300 MHZ frequency or wavelength is less than 1 meter) and microwave (greater than 3 GHZ frequency or wavelength is less than 0.1 meters) in the field of PCB, is on the microwave base copper clad using common rigid circuit board manufacturing method of a part of the process or the use of special processing methods and the production of circuit boards. In general, High Frequency PCB Board can be defined as a frequency above 1GHz circuit board.

With the rapid development of science and technology, more and more equipment is designed in the microwave frequency band (>1GHz) or even with the millimeter wave field (30GHz) above the application, which also means that the frequency is getting higher and higher, the requirements for the substrate of the circuit board are also getting higher and higher. For example, the substrate material needs to have excellent electrical properties, good chemical stability, with the increase of power signal frequency in the substrate loss requirements are very small, so the importance of High Frequency Board is highlighted.

PCB High Frequency microwave PCB board application field

1. Mobile communication products, intelligent lighting system

2. Power amplifier, low noise amplifier, etc

3. Passive devices such as power splitters, couplers, duplexes, filters, etc

4. In the field of automobile anti-collision system, satellite system, radio system and so on, the development trend of electronic equipment is high frequency.

The classification of High Frequency microwave PCB board

Thermosetting materials filled with powdered ceramics

Manufacturer: Rogers 4350B/4003C, 25N/25FR from Arlon, Taconic's TLG series

Processing method:

The process is similar to that of epoxy resin/glass woven cloth (FR4), but the plate is brittle and easy to break.

The life of the drill bit and gong knife should be reduced by 20% when drilling and gong board.

PTFE (polytetrafluoroethylene), teflon PCB.

The manufacturer

1. RO3000 series, RT series and TMM series of Rogers Company

2. Arlon's AD/AR series, Isoclad series, and Cuclad series

3. Taconic's RF series, TLX series and TLY series

4. Taixing Microwave F4B, F4BM, F4BK, TP-2

The processing method

1. Board Cutting: Protective film must be retained to prevent scratches and indentation

2. The drill:

A. Use a new drill tip (standard 130), the best is one in a stack, the presser bite pressure is 40psi

B. Aluminum sheet as the cover board, and then use 1mm melamine pad, tighten the PTFE teflon board

C. After drilling, use air gun to blow out the dust in the hole

D. Use the most stable drill and drilling parameters (basically, the smaller the hole is, the faster the drilling rate is; the smaller the Chip load is, the smaller the return rate is)

3. The hole processing

1. Plasma treatment or sodium naphthalene activation treatment is beneficial to metallization of poress

4. PTH

A. After micro-etching (the micro-etching rate is controlled by 20 micro-inches), the board shall be fed from the de-oil cylinder in PTH

B. If necessary, the second PTH will be performed and only need to start from the anticipated margaritops jar

5. The Soldermask

A. Pre-treatment: Acid washing board is used instead of mechanical grinding board

B. Pre-treatment and then baking board (90 degree Celsius, 30min), brush green oil to cure

C. The baking board is divided into three sections: one section is 80 degree Celsius, 100 degree Celsius and 150 degree Celsius, and the time is 30min for each section (if there is oil spilling on the substrate surface, you can rework it: wash the green oil off and reactivate it)

6. Outline Routing

The white paper is laid on the PTFE board circuit surface, and the top and bottom are clamped with FR-4 substrate or phenolic substrate with 1.0mm thickness etched to remove copper: as shown in the figure:

7. Process flow

A. NPTH PTFE board processing process

Material opening - drilling - dry film - inspection - etching - etch - solder resistance - character - tin spray - molding - test - final inspection - packing - shipment

B. PTH PTFE board processing process

Material opening - drilling - hole treatment (plasma treatment or sodium nthalene activation treatment) - copper precipitation - plate electricity - dry film - inspection - drawing electricity - etching - corrosion inspection - solder resistance - character - tin spray - molding - test - final inspection - packing - shipment

8. The summary

Difficulties in High Frequency Board processing

A. Copper sink: the hole wall is not easy to copper

B. Switching, etching, line width line notch, sand hole control

C. Green oil process: control the adhesion and foaming of green oil

D. Strictly control the scratch of the PCB board in each process, etc

Why do you need to choose the right microwave PCB manufacturer?

Ordering a microwave PCB board from a microwave PCB production plant equipped with high-tech equipment is more advantageous to a low-cost PCB manufacturing plant that uses low-grade materials.

Microwave PCB is very sensitive to factors such as noise, impedance, electromagnetic and ESds. High-quality PCB manufacturer focus on eliminating any influencing factors in the manufacturing process. Poor quality RF microwave PCBs are not expected to last long, which is why choosing a perfect RF microwave PCB manufacturer can change your product experience.

Today, most modern RF microwave PCB manufacturing plants use computer-aided engineering software simulation programs for PCB manufacturing. The biggest advantage of CAD-based RF microwave PCB manufacturing is that it has simulation models of various brands and PCB models with appropriate product specifications.

These parameters are essential for standardizing the production of RF microwave PCBs and ensuring reliability. In addition, these machines also support manual operation, allowing operators to perform manual operations.

Therefore, it is obvious that the manufacture of RF microwave PCB is not as simple as it seems.
