PCB Assembly

COMAAS provides the turnkey service for makers& startups to create the first prototyping board to the mass production, includes the PCB/ Components Sourcing/ Soldering/ Programming/ Testing and end shipping.

Just like PCB business, our PCBA services also specialize in prototyping and small-volume production, making COMAAS the one-stop destination of boards fabrication and assembly.

This arrangement makes your R&D work easy and time-saving. and thus can concentrate on the creating and designing.

How to use COMAAS PCBA service

1. Send your request to service@comaas.cc for quotation. For PCB Assembly work, Please send us the following information:

  • PCB Gerber Files, and the quantity you need and related spec such as color/ pads finish/ layers, etc.
  • BOM Files, some reference link or digikey/ farnell parts number would be help for our quotation.
  • Files for the soldering such as parts mapping for pick-n-place machine, or a simple mapping for hand soldering.
  • Programming/ Testing method, Makerfabs will help testing all the PCBA to ensure you 100% pass.
  • Other files that you want us know to avoid mistakes in the production.

2. COMAAS will make you quotation in 2 working days.

3. Custom’s checking on the quotation and confirmation, and negotiation if needed.

4. COMAAS works on the project.

5. Shipping, customer’s checking, and projects closed if all OK.

PCB Assembly and Price

Projects will be soldered manually or by pick-n-place machine, depends on the projects quantity and soldering difficulty. Basically, for prototyping board < 10 pcs, will be soldered by hand, while by machine with higher quantity. The price would be 0.03$ for each pads, both for SMD pads or THT pads. Note that a stencil would be needed for SMD soldering, even for hand soldering.

  • 1. PCB Cost and Stencil: PCB cost depends on quantity/size/spec,same as PCB Prototyping; and Stencil for SMD pads soldering. COMAAS will preserve the stencil for 3 month for customer re-production;
  • 2. Assembly Cost: Based on soldering difficulty and quantity;
  • 3. Engineer Starting fee: If some testing needed, the testing fee will be list here, based on the testing time, 0.1$/minute;
  • 4. Components: Customer can check the detailed quotation for each components in the quotation parts sheet;
  • 5. Shipping Fee: COMAAS provide direct shenzhen DHL, with 2~3 days to North America and 3~4 days to other place all the world.

All the detailed quotation will be prepared for customer before your final decision. As the components, we can solder the most common used package such as 0201/0402/0603/QFP/QFN/BGA/THT.

Quality Control

With more than 5 Years' experience in PCBA Production, COMAAS treat the quality the most important factor in our business, the testing include:

  • 1. Industry level PCB, All E-tested;
  • 2. Official components from distributors or mouser/digikey/farnell, etc.
  • 3. Prototyping sample before the mass Production for customer confirmation;
  • 4. 100% visual inspection: For quantity >100 pcs, AOI inspection, according to IPC-A-610E and GB2828 sampling standard;
  • 5. Functional testing include programming(customer provide testing method)
