Printed Circuit Boards Our Products
From a complex multi-layer board to a double sided surface mount design, our goal is to provide you a quality product that
meets your requirements and is the most cost effective to manufacture. Our experience in IPC class III standards, very
stringent cleanliness requirements, heavy copper, and production tolerances allow us to provide our customers exactly
what they need for their end product.
               Printed Circuit Board

Advanced technology products:
Backplanes, HDI boards, high-frequency boards, high TG boards, halogen-free boards, flexible and rigid-flex boards,
hybrids, and any boards with applications in high-tech products.

20 layers PCB, 2mil line width spacing: 
Our 10 years' manufacturing experience, high precision equipment and testing instruments enables Tortai to produce 20
layers rigid boards and rigid-flex circuits up to 12 layers. Backplane thicknesses up to .276 (7mm), aspect ratios up to
20:1, 2/2 line/space and impedance controlled designs are produced daily.

Products and technology application:
Apply to communications, aerospace, defense, IT, medical equipment, precision test equipment and industrial control
companies and more.
Standard criteria for PCBs processing: inspection and test criteria will be based upon IPC-A-600 and IPC-6012, class 2
unless otherwise specified on customer drawings or specifications.

PCB design service: Tortai also can provide the PCB design service to our customers. Sometimes, our customers only
give us a 2D file or just an idea, then we shall design the PCB, layout, and make the Gerber file for them
