Base Material ? FR-4 is the most popular substrate material for rigid PCBs.
Flex PCBs utilize a thin, flexible polymer film as the substrate for the circuitry. Flex PCBs reduce space consumption, and have lower weight.
Aluminum/copper core boards have better heat dissipation and thermal transfer than standard FR-4 constructions.
Note: For Aluminum/Copper core boards, the min drill size is 1.0mm, and min slot width is 1.6mm.
Rogers/Teflon PCBs have excellent dielectric properties and minimal resistance. They are generally used in high-speed, high-frequency circuitry applications.

Layers ? Number of copper layers.
Odd layer counts will be fabricated as the next even layer.

SMD StencilOrder a separate stencil together with your PCB.

Framework ? No (Non-framework): Foil only, lower cost.
Yes (Framework): With aluminum frame, easier for repeated printing.

Step Stencil ? Step stencils provide different solder paste volume for components that need different paste amounts on one PCB.
Currently two thickness levels are supported. If Yes, describe step regions in Remark.

Stencil Side ? Top only: 1 stencil, top side Gerber.
Bottom only: 1 stencil, bottom side Gerber.
Top+Bottom (Single): 1 stencil, both sides on one foil (size ≥ 2× PCB).
Top+Bottom (Separate): 2 stencils, price ×2.

Please select the Stencil Side according to your design requirements.

Dimensions ? Overall stencil size and valid working area.
Choose a size larger than your PCB.

Stencil Qty ? Number of stencils required.
Top + Bottom (Separate) forces quantity = 2. pcs

Thickness ? Choose thickness by component pad size.
Common default: 0.12–0.15mm.
Engineers can also select based on your files if needed.

Process Type ? Solder paste stencil: Most common for SMT.
Red glue stencil: For adhesive dispensing.

Polishing Process ? Sanding: Standard, general use.
Etching: Economical deburring.
Electropolishing: Smoothest surface, better paste release. Recommended for ≤0.5mm pitch IC / BGA. (+$12)

Fiducials ? Alignment marks for SMT machines.
Hand assembly usually does not need fiducials.
If required, select Etched Through / Half and include them in the design file.

Engrave Text ? Laser engrave text on the stencil (e.g. order #, file name).
If Yes but no text in Remark, file name and order # will be used.

Stencil Remark ? Step regions, 1:1 aperture request, PO number, engrave text, etc.

Notes:

① Stencil aperture openings follow factory standard by default. For 1:1 opening, leave a remark.

② Provide clear Gerber paste layers to reduce engineering questions.

PCB AssemblyHave your components assembled onto these PCBs.

Assembly Type ? Turnkey: We source all components and assemble the boards.
Kitted / Consigned: You supply all components, we only assemble.
Combo: You supply some components, we source the rest.

Board type ? We suggest choose to do panel if single PCB qty is more than 20pcs or any side of single board is smaller than 50mm.

We suggest choose to do panel if single PCB qty is more than 20pcs or any side of single board is smaller than 50mm.

Assembly side(s) ? Are the parts mounted on one side only or both sides?

* Quantity ? Please fill in total quantity of single PCBs. pcs

Please fill in total quantity of single PCBs.

* Pay attention

Contains sensitive components/parts ? Due to the diversity of components, there are usually many things need to be paid attention to while doing assembly, such as whether it needs to be baked before mounting, whether there are special requirements about welding temperature, corrosion resistance, humidity, etc. Our engineers will check all the information, but it is still inevitable that there will be omissions. So it'll be much better that you can highlight the special requirements in advance.

Depanel the boards to delivery ? It is also called sub-board shipment: the panelized PCB is divided into pieces and packaged separately to ship out after the assembly service.

Function test ? Functional testing (FCT) is the last manufacturing step of PCB creation. It makes sure the PCB works correctly and avoids assembly issues including shorts, opens, missing components or incorrect parts. Please note your functional test methods and detailed requirements in the remark if needed.

Conformal coating ? Conformal coating is a protective thin polymeric film applied to the PCB. It conforms to the contours of the board and is typically applied at 25–250 μm, providing protection against moisture, dust, chemicals and temperature extremities.

Firmware loading ? Firmware loading refers to the process of loading a previously written program (firmware) onto the chips on the PCB, so that the chips can function properly after assembly.

Press-fit assembly ? Press-fit assembly establishes mechanical and electrical connections between boards and components without soldering: connector pins are inserted into plated through-holes with a certain force. It avoids broken or cold soldered pins and improves reliability.

Box build assembly ? Also known as systems integration: a full process service from designing and manufacturing the enclosure, installing the PCBA, cables and cable harness assembly, and even electrical and/or pneumatic systems.

Cable wire harness assembly ? A cable assembly is a group of wires/cables covered by an exterior sleeve; a wire harness is a single cable covered by an exterior sleeve. We provide standard and simple wiring harness assembly, or custom wire harnesses and cable assembly at short turnaround times.

Package box ? Neutral box: plain packaging, no delivery note or receipt included, and no brand mark on the label or courier slip.
Custom box: customized packaging with your own design (extra cost / MOQ may apply).

Flying Probe Testing ? Flying Probe Testing (FPT) is a precise PCB electrical test using movable probes to check conductivity, shorts and component parameters. No fixtures needed, high precision and flexibility — ideal for prototypes, small batches and high-density PCBs.
Supported files: ODB++ (*.tgz), .PcbDoc; BOM: .csv, .txt, .html, .xls, .xlsx

Number of X-ray test ? X-ray inspection is a non-destructive testing technique used to inspect the quality of solder joint connections and component placement (especially BGA / QFN etc.).
