FAQ

Question Point Answer

Q: What information is required for PCB CEGSATE:
 Gberber files for PCB production, product process instructions, such as material requirements, surface treatment
requirements, finished product thickness requirements, PCB stack structure diagram for advanced products, copper
thickness requirements for each layer, sample quantity requirements, batch order requirements, product application
fields, and other related information are required

Q: What information does PCBA need to provide CEGSATE:
BOM report is required (including the brand, specifications, and model of the components), X and Y coordinate num
bers of PCBA components, and processing requirements: Do we need to purchase the components on our behalf?
Or customer supplied components?
Do you need software burning?
What is the required quantity?
What is the monthly demand and other detailed information.

Question: Is my file secure?
 CEGSATE: Your files are very secure, and we protect intellectual property rights for our clients throughout the entire
 process. All files provided by the customer will never be shared with any third party.

Q: What is the minimum order quantity? CESGATE: There is no minimum order quantity in POE. We are able to handle
 small and large batches flexibly.

Q: Do you have any other services? CESGATE: We mainly focus on PCB+FPC production+SMT+assembly PCBA+com
ponent procurement services; In addition, we can also provide programming, testing, software burning, wiring, and
 shell assembly services; And product design, product development, software development

Q: What is your inspection method? How do you control the quality? CESGATE: In order to ensure the quality of PCB
 and FPC products, flying pin testing is usually used for samples and small batches; The inner circuit undergoes AOI
optical inspection, online AOI inspection, and the finished product undergoes 100% inspection through E-SET testing
rack. The appearance undergoes 100% inspection through fully automatic finished product inspection equipment and
FQC. PCBA undergoes automatic optical inspection (AOI), BGA part X-Ray 100% radiographic inspection, and first arti
cle inspection (FAI). PCBA products that require software burning undergo 100% full testing through finished product
testing rack according to product functional requirements.
