How an order runs
-
Send your files
Gerber or ODB++, drill file, stackup and target impedances. A PDF drawing helps.
-
DFM and stackup review
An RF engineer checks etch compensation, stackup, material stock and tolerances, and sends a report with the quote.
-
Fabrication
Lamination, drilling, PTFE hole treatment, plating and imaging with per-panel etch compensation.
-
Test
Electrical test on every board, TDR on impedance coupons, and microsections per lot.
-
Ship
Vacuum packed with test report, certificate of conformance and laminate lot certificates.
From the engineering hub
Short, practical notes on laminates, stackups and mmWave layout, written by the people who build the boards.
Materials
RO4350B or RO4003C: choosing between the two workhorse laminates
Same resin family, same FR-4-like processing, different loss and flame rating. How to decide in two questions.
Manufacturing
Hybrid PTFE and FR-4 stackups without warpage
Putting RF laminate only where the RF runs saves money. Keeping the board flat takes symmetry, the right bondply and a lamination plan.
Design
Microstrip or grounded coplanar waveguide above 20 GHz
Microstrip is easy until it starts to radiate. What grounded coplanar waveguide fixes, what it costs, and how tight the via fence has to be.
Every lot ships with electrical test data, TDR coupon results, microsection images and laminate certificates.
