Introduction of PCB with different solder resist colors
Solder resist layer is the main protection layer of the board against corrosion and oxidation, without the protection of the solder layer, the performance of the PCB will degrade, shortening the normal working life of the equipment; more importantly, in the PCB assembly process, the solder resist layer provides a barrier between the solder joints and other conductive components of the printed circuit board, helping to prevent the formation of solder bridges.

Role of solder resist layer
1. In the soldering process, the gap between the pads and pads is very small. Solder resist layer can prevent short circuit between pads and pads.
2. Only let the PCB solder where it must be soldered.
3. Solder resist layer prevents insulation degradation and corrosion caused by environmental factors such as dust and moisture. Solder resist layer can protect the line for a long time.
4. The solder resist layer is highly insulating and can densify the circuit.
FAQ
Q1. What documents do you need to prepare if you want to get a quote from us?
A: PCB boards need to prepare Gerber files, including RS274X, ODB++, DXF, PCB, PCBDOC and other formats.
For PCBA (PCB with soldered components), in addition to the files of PCB, you also need to prepare BOM list (component list), Pick and Place file (txt format), physical sample drawing or 3D PDF version file, etc.
PCB layout requires a PCB schematic and PCB outline drawing.
For PCB design, you need to express your ideas and we will discuss whether we can implement your ideas.
Q2. Do you have a minimum order quantity?
A: We have the flexibility to handle both small and large volume production. We do not have any minimum order quantity, and the smallest order we accept is 1 piece.
In general, the higher the quantity produced, the lower the unit price and the longer the delivery time.
Q3. How can we keep our product information and design documents confidential?
A: Your files are completely safe and secure. We protect the intellectual property of our clients throughout. All files from our clients are never shared with any third party.
Q4. How long is the delivery time?
A: The production time for standard PCB samples is 1-7 days, 7-10 days for small batch production, and 12-25 days for large orders.
For the production of non -standard PCB and PCBA, please send the reference file and production requirements to sales@pcbfactorysmt.com，we will reply to you as soon as possible.
Q5. What are the main products of your PCB / PCBA service?
A: Industrial control, automotive, medical equipment, communication electronics, aviation, LED...
Q6. How long does it take for PCB and PCBA quotation?
A: PCB quotation can be completed within 0.5-2 hours PCBA depends on the number of components, simple can be completed within 6 hours, complex 12-36 hours can be completed.
Q7. Shipping fee?
A: Usually we offer EXW, FCA, FOB, CIF and DDU terms, if there is no special request, the default terms quoted are FOB Shenzhen. Please mention the terms and conditions when you have any request.
We work with courier companies including DHL, FedEx, UPS, TNT and EMS, with air and sea freight also optional.
Shipping costs are determined by the destination, weight, and package size of the shipment. If you need us to quote the shipping cost, please let us know.
Q8. Do you accept process materials from customers?
A: Yes, we can source components and we accept components from our customers.
