Measurement of solder crack rate by cross-sectional observation.
Calculating the crack rate of ball joints and implementing it according to customer specifications!
After the solder durability test on the circuit board, if cracks occur in the solder joints, the crack rate will be calculated to confirm whether the cracks are within acceptable standards. The evaluation criteria after the solder durability test can be individually established based on the product environmental specifications, so most customers have their own standards. The measurement methods vary according to the shape of the components, but when you make a request, we will carry out the tests according to your specifications. 【Service Contents】 ■ Solder joints of BGA - Calculation of crack rate for ball joints ■ Solder joints of chip resistors - Calculation of crack rate for both ends of square and rectangular terminals ■ Solder joints of coil components - Calculation of crack rate for ribbon leads and QFP leads *For more details, please refer to the PDF document or feel free to contact us.
