FAQ
Q1. How do you ensure the quality of BGA solder joints?
KING FIELD: Firstly, we do the nano-coated laser stencil and later inspect SPI thoroughly. We also carry out nitrogen reflow soldering so as to reduce the oxygen content. And at the end, using X-ray inspection equipment, we check the void ratio inside the solder joints.
Q2. How does your BGA enhance signal transmission speed?
KING FIELD: Since BGA involves solder balls which physically connect the chip and the PCB, the signal path is thus kept as short as possible, and the signal delay is drastically lowered as a result.
Q3. How do you do safe BGA rework?
KING FIELD: Through our experienced rework station, it is possible to desolder and re-insert BGAs without causing harm to the board and other components.
Q4. What measures do you take to avoid stress cracking?
KING FIELD: We apply filler glue to the bottom of large BGAs post reflow soldering; also, if our engineers have customers' thermal solutions, they will perform joint evaluation of the thermal solution.
Q5. What is the consequence of not cleaning the BGA bottom very thoroughly?
KING FIELD: Yes, inevitably. Residue of the flux may result in a short circuit. With a water wash/semi-water wash and ultrasonic cleaning equipment, we can clean the surface.
