Can I have overlapping drills on my board?
Yes, overlapping drills are supported.
Can my PCB have silkscreen on both sides?
Yes, included at no extra cost.
What PCB materials and finishes are available?
We work with FR-4, Rogers, Polyimide, Aluminum Thermal Clad, ISOLA, Taconic, Arlon, NAN-YA and more. Finishes include ENIG, Immersion Silver, Immersion Tin, OSP, HAL (lead-free or leaded), soft bondable gold, and ENIPEG.
What are your minimum hole sizes and trace/space?
Laser-drilled holes down to 0.004″, mechanical holes to 0.005″. Trace/space as low as 0.003″, depending on copper weight.Laser-drilled holes down to 0.004″, mechanical holes to 0.005″. Trace/space as low as 0.003″, depending on copper weight.
We build up to 50 layers.
Yes, we manufacture HDI boards with laser-drilled microvias. Learn about HDI
What is the maximum PCB layer count you can fabricate?
We build up to 40 layers.
Do you assemble BGA? Any special requirement on this?
Design Requirements:
Via-on-pad: Must be resin-filled for reliable soldering.
Via-near-pad: Must be tented/solder-mask-filled to prevent defects.
We ensure high-quality BGA assembly through strict process controls.
Can you source some parts for my assembly?
Yes. This practice is called partial Turn-key. You can supply some parts, and we source the rest of the parts on your behalf. We will ask for your approval for anything that is not sure at our side. In case parts crossing or substitution is needed, we will again ask for your final approval.
What are the techniques used in SMT Assembly?
SMT Assembly involves the following
Application of solder paste
Placing the components
Soldering the boards with a reflow process.
What is the lead time on a turn-key order?
The total lead time depends on component procurement and PCB assembly. To optimize efficiency, we overlap processes: once we receive your Gerber files and BOM, we begin stencil preparation and PCB fabrication in parallel with parts sourcing.
How do you order components for my PCBA projects?
We order components in bulk if they are common and out of stock. For standard parts we typically keep in inventory, you pay little or nothing.
For uncommon BOM items, we procure a 5% overage or 5 spare parts (based on size/cost) to prevent shortages due to production loss—covered at our cost, so you incur no extra charges.
If any BOM issues arise (e.g., high MOQs), we’ll collaborate on solutions. Our 35-member sourcing team ensures 24-hour to 7-day quotes (depending on BOM complexity) and procures parts globally, leveraging long-term local supplier relationships (10+ years) and international channels for competitive pricing.
What kind of file format can you accept?
We can process Gerber RS-274X and ODB++ files.
