How to Handle the Wire Bonding for Rogers RO4350 PCB?

With wire bonding, you will be able to interconnect the semiconductor equipment or integrated circuit to your package, whenever you are fabricating.

Also, you can utilize wire bonding for the interconnection of different printed circuit boards. The methods used include true fusion welding and diffusion bonding

Diffusion Bonding

This has to do with the creation of joints, but doesn’t involve welding. Now, the standard techniques for diffusion bonding include: Ultrasonic welding, thermal compression, and thermosonic bonding

True Fusion Welding

This involves the melting of circuit pads and lead metal together. These include soldering, electric beam welding, laser welding, percussive arc welding, parallel gap welding, and resistance welding.

Guidelines for PCB Fabrication when Constructing the Rogers RO4350B PCB

Follow the below tips to help you during the Rogers 4350B PCB construction.

Preparation of the inner layer

The Ro4350B works with different pinless and pinned tooling systems. Therefore, this choice depends on the circuit’s capabilities and preference as well as the final registration’s requirements.

Make use of chemical processing when working with the thinner cores. For the thicker cores, make use of mechanical processing. This prepares the material surface for photoresist processing and copper etching.

Also, check the guidelines that accompany that specific adhesive prepreg or system whenever you are choosing copper oxide or a different oxide treatment.

Furthermore, follow the guidelines for the adhesive systems for multilayer bonding. This is because the Rogers 4350B laminate works fine with many thermosetting and thermoplastic adhesive systems.


When drilling, you can make use of standard exit or entry materials. The drilling speed you should use should be below 500SFM.

Metal Deposition

There is no need to conduct any unique treatment before you go ahead to metalize the RO 4350B. Also, you can consider the copper flash plates even before you image boards with holes having an aspect ratio that is high.

Outer Layer Processing and Copper Plating

You can make use of the standard lead/tin plating, electrolytic tin, pattern and panel processing, and acid copper. After the plating, you can use the SES method to process your laminate.


Use standard room temperatures to store your laminates. This ranges between 10 and 30C. Also, don’t allow excess humidity to gain access to it. This will cause the material to experience oxidation.
