Change in the composition of BGA solder from lead-free to eutectic solder [Case Study]

I want to change the composition from lead-free solder balls to eutectic solder balls! We will solve your concerns about solder composition changes!

In the composition change of K-All's solder, we will switch from lead-free balls to eutectic balls. If the solder specifications of the substrate and the solder balls of the BGA differ, unexpected troubles may arise. K-All also conducts work to prevent implementation troubles by removing solder with different specifications and then attaching solder balls that match the specifications. We propose a reliable method while making use of your existing BGA. 【Features】 ○ Specification change from lead-free balls to eutectic balls ○ Preventing implementation troubles in advance through composition changes ○ Proposing a highly reliable method For more details, please contact us or download the catalog.

basic information

【Case Examples】 [We want to change the composition from Pb-free solder balls to eutectic solder balls] ○ We have a track record from 1 piece to 10K The finished state is within the specified standards. * We have experience changing from eutectic solder balls to Pb-free solder balls. When changing from eutectic solder balls to Pb-free solder balls, the customer conducted an analysis investigation. * If the heat resistance temperature of the device is lower than the melting temperature of Pb-free solder, there is a risk of device damage. * We have a large stock of metal masks and solder balls (φ0.76mm to 0.25mm, Pb-free, eutectic) with pitch sizes from 1.27mm to 0.4mm. [We want to reball during BGA rework] ○ Reballing occurs for failure analysis, with many cases where failure is not an option. * With over 30 years of reballing experience, we pride ourselves on a 99% reballing success rate. * Cream solder is used at the joint between the ball and the substrate, and we have gained trust exceeding product standards regarding strength. * Basically, reballing is performed using cream solder. ● For more details, please contact us or download the catalog.
