Minimum aperture up to 0.1mm for high-density interconnection (HDI) build-up multi-layer PCB,
with electrical conduction between wirings on each layer controlled through interlayer vias. Currently laser
drilling machines are extensively applied in processing of the Interlayer via-holes.
Real-time monitoring of chemical quality in copper plating sinks.
The aim of electroless copper is to plate a conductive layer through a hole or into a blind microvia.
Using the vacuum etching technology to make sure that both surfaces of the board are very uniform.
it produces a straighter conductor profile, allowing the resulting plate to more accurately match the wiring requirements.

I get my second order. I'm very happy with this PCBs, again a good work. The cutting and soldering are professional, and have a safe BOX for the post services!!! Thank You PCBGOGO. I order again from You ! Best wishes, Richard from HUNGARY
This was my first PCB at PCBgogo. A 4-layer one. And I have to say that I'm really surprised by the overall process of this order. I had some issues with my files and they told me about this only a few hours after the order was sent. Once fixed, it took only a few days to have the PCB delivered, as stated on their website. Quality is perfect, edges are smooth, silkscreen drawings are perfect as well. Price is way below other suppliers for the same quality. Even with small batches. I have already ordered another PCB and next step will be the complete assembly. I greatly recommend their service and PCBgogo will now be my default supplier.
Jarsine and afterword Eric has been my contact person on this project. We encountered a problem on the PCB which Eric informed we prior to assembly as my gerber files were incorrect. Eric handled all my queries and adjustments without any hesitation and the utmost professionalism!
