I'm doing lead-free SMT of BGA with 450 micron ball. I found there are lots of voids under xray, there are around 2-3 voids in every balls. It is around 10% of volume ratio. I would like to ask if anyone know there is any standard of acceptable maxim

Yeah, that's what I'm doing now. I have it now peaking around 235, with about 70 sec. above 220C. (220C is the reflow temp, according to manufacturer. I've always used 217C for Pb free) Wish me luck. Thanks!

New Technology for Void-free Reflow Soldering
Industry News | 2024-10-06 08:00:38.0
In the world of electronics manufacturing, soldering plays a critical role. The PCB reflow oven process has revolutionized the industry by improving the quality of solder joints, especially for high-reliability applications like aerospace, automotive, and medical devices. But what exactly is this process, and why should manufacturers consider it?

Due to the ongoing trend towards miniaturization of power components, the need for increased thermal conductivity of solder joints in SMT processes gains more and more importance. Therefore, the role of void free solder joints in power electronics becomes more central. Voids developed during soldering reduce the actual thermal transfer and can cause thermal damage of the power components up to their failure. For this reason, the company has developed a new technique to minimize the formation of these voids during the soldering process.

Solder voiding is present in the majority solder joints and is generally accepted when the voids are small and the total void content is minimal. X-ray methods are the predominate method for solder void analysis but this method can be quite subjective for non grid array components due to the two dimensional aspects of X-ray images and software limitations. A novel method of making a copper "sandwich" to simulate under lead and under component environs during reflow has been developed and is discussed in detail. This method has enabled quantitative solder paste void analysis for lead free and specialty paste development and process refinement. Profile and paste storage effects on voiding are discussed. Additionally an optimal design and material selection from a solder void standpoint for a heat spreader on a BCC (Bumpered Chip Carrier) has been developed and is discussed.
