Re: PCB fab for SHF laminates with immersion silver plating and solder resist?

Neil Smith G4DBN
 

No duty on Eurocircuits, and they charge UK VAT, so there isn't much of an advantage for UK fabs.  The awkward bit is that for 100+ boards, most fabs prices start to level off, but in the 10-30 quantity, the UK fabs I've asked before were just wanting silly money and it rather put me off asking again.

Does anyone have experience of PCB fabs who can do immersion silver finish on Rogers, Arlon, Isola and similar SHF laminates? I've had a quote from Eurocircuits and I've used them previously. I know there are some Chinese fabs that can do silver, but it is an expensive business and I want to be 100% sure of the quality.

I need the boards milling with rounded corners and a pocket for the devices.  I'd like solder resist if that is an option, so I can do reflow of the passives and thermal monitor chips without them sliding about the place.

Price for a 40 x 40 mm board in 30-off, with milling, silvering and resist on an I-Tera laminate is about £12 each for 5 day service from their Hungary/Germany fabs. Rogers 4350 is about £2 extra. RO4003C needs a special quote. Anyone know of a supplier with these capabilities that offers better pricing?

Sounds expensive! I'll have to send them some sample Gerbers and see what price they come up with.

Minnitron in Ramsgate may be worth asking for a quote - http://www.minnitron.co.uk

I've used their prototyping service (pcbpanel.co.uk ) and the quality and turnround was good and the price very competative for a UK manufactuer. Unfortuanately they don't do Rogers on the prototyping service.

I asked them about Rogers 4033C and 4350B and they carry both as standard stock items but I haven't sent them any designs for quote as yet so I can't comment on price. I'll be doing that in the next week or so and can let you know if their standard service is as competative as their protypes.

Re: PCB fab for SHF laminates with immersion silver plating and solder resist?

Ah, good point.  I was thinking about coplanar waveguide with fences of vias at each side rather than isolated microstrip, with narrow gaps so there are significant fields through the air, for an effective epsilon_r of the average of the substrate and air. Perhaps that might not be worth the extra effort at 10 GHz, even at 40+ watts? I had almost convinced myself to try direct waveguide launch from a probe milled from the PCB, but I had a lie-down and thought better of it.

I've seen several boards with vapourised output microstrips cause by thermal cycling and delamination so I want to avoid any thermal issues if at all possible, even though I'll be using fluid cooling on these.

I'm currently being quoted 16 August 2021by RS  for stock of the LDMOS device used in these kits.

I have no stock, but 30 on order and plenty of PCBs and the other parts.

If you want to avoid the rush in August, I'm happy to take pre orders for kits until then. - No need to pay until I have the devices, just email me to reserve a kit, I'm not planning a price increase.
