high frequecy pcb manufacturing


With the popularity of 5G technology, the market has a growing demand for high-frequency materials,Rayming stock high frequncy materials for years,  We have delivered lots projects of mircowave or RF pcb design

Material: Most Rogers material is in stock like rogers 4350b ,3003,4003, 5880,some Teflon,taconic,arlon,isola,dupont,nelco  is available,others if you accept delivery time is fine for us to manufacture

flexible pcb manufacturing


Prototype and production flexible and rigid-flex PCB manufacturing services. Get low-to-high volume rigid-flex, and flex PCB quantities manufactured with industry leading quick turnaround times 

Flexible PCBs with 8 layers rigid PCB, Single-Sided Flexible with rigid PCB board up to 6 layer, Double-Sided Flexible PCBs with 4 layer to 12 layer rigid pcb, Multilayer Flexible PCBs with multilayer rigid PCB



HDI PCB are one of the fastest growing technologies in the PCB industry. HDI stands for High Density Interconnector.HDI PCB manufacturing is a precise job with Blind or/with buried hole should control.

RayMing HDI PCB Structures: 1.  1+N+1 – PCBs contain 1 “build-up” of high-density interconnection layers. 2.  i+N+i (i≥2) – PCBs contain 2 or more “build-up” of high density interconnection layers. Microvias on different layers can be staggered or stacked.
