 1. What data are needed for PCB production?
|
| It is best to provide data in Gerber 274-X format. In addition, Cam350, CAD, Protel 99se, PADS, DXP and Eagle can also be processed. |
| 2. What kind of PCB orders is of most competitive?
|
| Orders of fast sample boards, bulk and multi-layer samples with price advantage, as well as and special panel veneers |
| 3. What is your main business?
|
| Production of rigid boards, soft boards, rigid-flex boards and stencils as well as SMT processing and assembly |
| 4. How about the delivery time of Sandeying products?
|
| Currently, for the normal products, such as the sample boards less than a square meter, the delivery cycle is such that, 5 days for 2-layer boards, 6 days for 4-layer boards, 7 days for 6-layer boards, 8 days for 8-layer boards, 10 days for 10-layer boards, 10 days for 12-layer boards. If the delivery cycle still fails to meet your current demand, we can arrange for expedited services for your products to finish 2 to 4 days in advance on the basis of the present delivery cycle. I think such a delivery time will definitely be able to meet the delivery requirements for your current products. |
| 5. How do you charge for expedited services?
|
| The expedited fee is to be determined depending on the processing difficulty of the boards and the actual situation of the production line, and it is necessary to provide data for specific offer. |
| 6. What kind of boards can you process?
|
| Common FR4, high-TG and halogen-free boards, Rogers, Arlon, Telfon, aluminum/copper-based boards, PI, etc. |
| 7. How are the orders of PCBA manufacturing sample boards achieved and what are the advantages?
|
| The orders of PCBA manufacturing sample boards in our company refer to the orders with the specified batch number less than 100PCS. The welding mode for such orders is the same way as that of large-batch orders, and the whole-process machine welding mode is adopted. The advantages of adopting the machine welding mode are that, the consistency of product quality is good; the uncertainty factors of products caused by manual welding are resolved, thus to affect the judgment in product development stage; the mode of analog product batch manufacturing improves the adaptability of products imported into batch manufacturing, etc. |
| 8. How about the SMT manufacturing process and capability of PCBA?
|
| Currently, for the manufacturing of sample boards, small batch and batch orders, the high-precision placement can be easily completed by adopting the conventional process. For example: The smallest placement size of CHIP elements is 0201; and the center-to-center distance of the adjacent solder points of BGA elements can achieve 0.4mm. |
| 9. How about the delivery capacity of PCBA manufacturing?
|
| PCBA manufacturing is a comprehensive service. The delivery capacity depends on the manufacturing cycle. Taking the conventional industrial control products for example, for the sample board orders, the conventional manufacturing cycle is that the delivery is made three days after of the material are well prepared; for small batch orders, the delivery is made in 4 to 5 days; and for large batch orders, the delivery is started after three days, and the daily quantity delivered is not less than 5000PCS. At the same time, our company also provides customers with manufacturing services for expedited orders. The expedited project is followed up by the engineer in the whole process, to ensure product quality. |
| 10. How about the quality of PCBA manufacturing?
|
|
The PCBA manufacturing quality is closely related with product design, quality control of materials and welding process control. As for our welding process control, the yield rate of orders of sample boards off the production line can be controlled to less than 300 PPM. For batch orders, the products are tested directly after getting off from the production line, and the yield rate can reach 99.5%. |
