FAQ
Q1 : What size components can you mount?
KING FIELD : Our placement equipment has an accuracy of ± 0.015mm and supports precision components such as 01005 and 0.3mm BGA .
Q2 : Can you balance rapid prototyping and stable mass production?
KING FIELD : We have a dedicated new product communication channel that can respond to your needs 24 hours a day . Only after the prototyping parameters are finalized will we upload them to the MES system for final mass production .
Q3 : Can we trace the problem if there is one?
KING FIELD : Yes. Our MES system is linked to the PCB barcode, allowing us to check material loading records, actual oven temperature profile records , and SPI/AOI inspection data.
Q4 : Have you done any special processes such as high frequency, heat dissipation, and underfill ?
KING FIELD : Yes, we have. We have experience in manufacturing special processes such as high frequency boards, aluminum substrates, and underfill . We can also ensure long-term reliability of special processes such as selective wave soldering, lamination, potting, and conformal coating .
Q5 : How do you manage valuable materials and humidity-sensitive components ?
KING FIELD : We have temperature and humidity controlled warehouses , as well as dedicated vacuum packaging and dehumidifier cabinets. Each material is labeled with its lifespan after being unpacked.
