7.How do you control your product quality?
We have professional personnel on each production line to carry out strict quality control. And professional QC and QA teams. Passed ISO9001 and IATF16949 product control certificate and ROHS product test report
8.What are our raw material price and quality advantages?
The PCB materials used in our factory are all in compliance with IPC standards. There are domestically produced materials and foreign-produced materials. If the customer does not have material model requirements, we will give priority to using our domestically produced materials, so that the price of the materials is relatively cheap.
9.Can you make pcb according to my sample board?
If you only have one sample board in hand, we can also help you extract production documents through your sample board, then help you mass production
10.Can you help with design?
Yes, we have a professional design team. If you have only one idea, we can help you implement the schematic design, the circuit diagram design, the Gerber file design. Build a professional team for you according to your needs.
11.How do you ensure our long-term business relationship?
We are sincerely hoping to establish the good long-term business relationship with our esteemed clients, so we will do our best to guarantee our customers' benefit, stable quality and competitive prices are essential,and we are also provide our increasingly advanced technology for our clients to meet the increasing needs in the current markets
12.PCB storage cycle
The storage period of PCB is mainly distinguished by surface treatment.
HAL, LF-HAL, Immersion Gold or ENIG surface process: shelf life 1 year
OSP, Immersion Silver, Immersion Sn: shelf life 6 months
Storage conditions: temperature 20-28 ℃, humidity ≤80%, vacuum packaging
13.Baking parameters before SMT patch
Requirements: The temperature is 120±5℃, generally baked for 2 hours, starting from the time the temperature reaches the baking temperature.
Temperature and time:
1. For the sealed and unsealed products with a manufacturing date within 2 months and more than 5 days, bake at 120±5℃ for 1 hour.
2. For the manufacturing date between 2 and 6 months, bake at 120±5℃ for 2 hours.
3. For the manufacturing date between 6 months and 1 year, bake at 120±5℃ for 4 hours.
4. The baked circuit board must be mounted within 5 days, and the unfinished ones need to be baked for another hour
before they can be put on the machine.
