- 5. Your specific requirements, or some reminds to avoid mistakes;
- 6. Your shipping address and shipping method you want , HK DHL/Shenzhen DHL/FedEx/register air mail supported;
- PCB fabrication is for the PCB cost, Elecrow will make the quotation based on the PCB layer, dimension, pads finish, and your other requirements. Besides, a stencil is needed for SMD soldering. The stencil is used for the soldering of SMD components. It will be kept in our company for three months. It won't be shipped with the assembled boards without extra requirement.
- PCB Assembly is the for the solder cost. Elecrow will charge the soldering fee based on the quantity of pads, with discounts depend on the quantity and soldering difficulty;
- Engineer Start fee is for the engineer start, will be $10-$100 for each project.
Component Sourcing fee needs $0-$50 for each project, this sourcing fee will return if bulk order(quantity more than 100pcs) placed.
- Components fee is the fee of components that Elecrow provided. Elecrow can provide & source most of the main components& modules. Customers can check the detailed components quotation in the “parts” sheet of quotation file.
- Shipping: Elecrow provide most of the popular shipping service such as HK DHL/Direct DHL/ FedEx/Registered Air Mail. Please leave us your shipping address for the shipping quotation. Note that the 300$ free shipping policy do not apply to the PCBA service.

As the customer requirements, we can solder the PCBA with hand or with reflow oven. For quantity>50 pcs, we will use the pick-and-place machine to place the components. Besides, lead free soldering available for the ROHS compatible. Part mapping file maybe needed for the components placement with pick-and-place machine.
As the cost, the soldering cost will depend on the quantity of Pads, 0.03$ for SMD Pads(with stencil) and 0.04$ for THT pads, with discounts based on the quantity; for prototyping round less than 20 pcs, 5$ will be added for each design.
