What This Equipment Means for Your Order
60 six-spindle CNC drilling machines
Drilling is the classic bottleneck in PCB production. With this much drilling capacity, prototypes and volume orders don't compete for the same machines — lead times stay stable.
5 LDI direct-imaging systems
Laser direct imaging is the hardware behind our 0.075 mm (3 mil) fine-line capability and accurate layer-to-layer registration on multilayer boards.
12 flying-probe testers
Prototypes and small batches are electrically tested without building a dedicated test fixture. Every board ships 100% electrically tested.
Automated PTH & pattern-plating lines
Automatic copper deposition and pattern plating keep hole-wall copper uniform from panel to panel — consistent through-hole reliability, batch after batch.
3 vacuum lamination presses on-site
Multilayer lamination runs on our group campus and is never outsourced to third parties — registration and pressing quality stay under one roof.
Complete in-house test lab
Impedance, microsection, RoHS, ionic-contamination and high-temperature testing are all done in-house — test data available with your shipment on request.
This equipment feeds our IQC / IPQC / FQC / OQC inspection process — see how it all fits together on the Quality Assurance page.
