Rogers 4350 High Frequency PCB

Hello Everyone,

Today, we’re going to talk about?high frequency PCB built on RO4350B?laminates.

?

Rogers RO4350B materials are proprietary woven glass reinforced hydrocarbon/ceramics with electrical performance close to PTFE/woven glass and the manufacturability is similar to epoxy/ glass.

RO4350B PCB has a dielectric constant of 3.48 at 10 GHz, a dissipation factor of 0.0037 at 10 GHz. Low dielectric tolerance and low loss allows applications with higher operating frequencies.

?

The expansion coefficient of RO4350B PCB is similar to that of copper that allows the board exhibiting excellent dimensional stability.

?

And RO4350B boards have a Tg of >280°C (536°F) so its expansion characteristics remain stable over the entire range of circuit processing temperatures.

?

For RO4350B?PCBs, we can provide you with single sided?board, double sided?board, multi-layer board and hybrid types.?RO4350B PCBs have wide thickness. There are the standard thickness such as 10 mils, 20 mils, 30 mils, 60mils etc. and non-standard thickness such as 4?mils, 6.6?mils,13.3?mils?and 16.6?mils etc. Finished copper on PCBs is?1oz and 2oz.

?

Our maximum PCB size?on high frequency materials?is 400mm by 500mm, it can be a single board in the sheet and also can be different designs in this panel. Solder mask of green, black, red and yellow etc is available in house.

?

There’s immersion gold, HASL, immersion silver, immersion tin, bare copper etc. for pads plating.

?

RO4350B?laminates are often used to manufacture multi-layer PCBs. The easiest method is that multi-layer boards are built on different cores and combined through bonding ply material?--- RO4450F.

?

In order to save production cost without reducing signal loss in high frequency environment,?RO4350B?can be pressed with FR-4 epoxy glass substrates.?The high frequency material is used in signal layer and FR-4 is used in other track layers.

RO4350B PCBs can be fabricated using standard FR-4 processes at lower fabrication cost. It's well suited for volume manufacturing process and benefit from the competitively price.

?

OK. This concludes the episode (5). Thank you for your watching.

See you next time.
