Dimensional Stability

It is a property necessary for the construction of mixed dielectric multilayer PCB boards. The low CTE of RO4350 laminates on the Z-axis provides reliable through hole quality even in severe thermal shock applications. The material of the RO4350 series has a TG of more than 280 ° C (536 ° F), so its expansion properties remain stable at all process temperatures in the circuit. RO4350 Series laminates can be easily converted into printed circuit boards using standard FR4 circuit board processing techniques. Unlike high-performance PTFE-based materials, RO4350 series laminates do not require special preparation processes such as sodium etching. This material is a rigid, heat-stable laminate that can be treated with automated handling systems and washers used to make the copper surface.
RO4350 laminates are currently available in a variety of 1080 and 1674 glass fabric models, all of which meet the same laminated electrical performance specifications. Designed specifically for direct replacement of RO4350 material, RO4350 laminates use RoHS compliant flame retardant technology for applications requiring UL 94V-0 certification. These materials meet the requirements of IPC-4103/10 single sheets for RO4003C and /11for RO4350.

Rogers PCB Production Guidelines

RO4350 high-frequency circuit materials have been developed to provide high-frequency performance comparable to woven PTFE glass substrates, which simplifies fabrication with epoxy/glass laminates. RO4350 is a thermoset material filled with hydrocarbon/glass reinforced ceramic with a very high glass transition temperature (TG> 280 ° C). Unlike PTFE-based microwave materials, no special treatment or via is required. As a result, the processing and assembly costs of the RO4350 material circuit are comparable to those of the epoxy/glass laminates.
Here are some basic tips for dealing with RO4350 double-sided plates. In general, the parameters and treatment methods used for epoxy/glass plates can be used to treat RO4350 plates.
Input / Output Rogers PCB Material
Inlet and outlet materials must be flat and rigid to minimize copper burrs. Recommended input materials are aluminum and rigid composite panels (0.254 to 0.635 mm). Most conventional starting materials with or without an aluminum coating are suitable.
Maximum Height of The Battery
The thickness of the material to be drilled must not exceed 70% of the groove length. This includes the thickness of the input material and penetration into the substrate.
Surface speeds of more than 500 SFM and chip load less than 0.05mm (0.002″) should be avoided as much as possible.
