Any recommendations/data on a superior flux to use for Package on Package assembly? Also, any guidelines on flux depth, viscosity, etc... are welcome.

Hi smtdude- I'm no expert at PoP (yet!) as we've only done a few weeks worth of experiments for a new customer but what i can tell you is 25-50% of the ball height (not diameter) is a good rule of thumb for the flux depth, at least to start. I can s

A novel epoxy flux EF-A was developed with good compatibility with no-clean solder pastes, and imparts high reliability for BGA assembly at a low cost. This compatibility with solder pastes is achieved by a well-engineered miscibility between epoxy and no-clean solder paste flux systems, and is further assured with the introduction of a venting channel. The compatibility enables a single bonding step for BGAs or CSPs, which exhibit high thermal warpage, to form a high-reliability assembly. Requirements in drop test, thermal cycling test (TCT), and SIR are all met by this epoxy flux, EF-A. The high viscosity stability at ambient temperature is another critical element in building a robust and userfriendly epoxy flux system. EF-A can be deposited with dipping, dispensing, and jetting. Its 75°C Tg facilitates good reworkability and minimizes the adverse impact of unfilled underfill material on TCT of BGA assemblies.

With the advancement of the electronic industry, package on package (POP) has become increasingly popular IC package for electronic devices, particularly POP TMV (Through Mold Vials) in mobile devices due to its benefits of miniaturization, design flexibility and cost efficiency. However, there are some issues that have been reported such as SIR drop due to small gap between top and bottom components, difficulty underfilling and rework due to stacked IC components and process yield issues. Some suppliers have reported using some methods such as dipping epoxy paste or epoxy flux to address these issues, but so far no customer has reported using these methods or materials in their mass production. In order to address these issues for POP TMV assembly, YINCAE has successfully developed and commercialized the first individual solder joint encapsulant adhesive for mass production for years.
With the Spectrum II's new Precision Z-axis, smaller dots and thinner solder paste lines can be achieved. This capability is standard on all Spectrum II systems and replaces the Precision Z option on the older Axiom products. In order to achieve su
