SAC305 Will be the best choice with minimum TAL, Maximum Soak Solder Profile. Surely your solder Joint strength also will be more reliable & This can pass any kind of reliable Tests.

Hi Peter, which should be the best cooling rate once belove TAL by using L-F alloy ie. SAC 305 ? Tnks GS

Hello, We are facing solderability issues on a particular lot of board. THe Nickel thickness measured with an XRF is around 400 U inches. Spec calls out for 130 u inches Nickel and 3 - 5 U inches gold over it. Assuming there is no porosity on the g

Hi All, I'm using 8 zone reflow for ROHS 0.2mm Thick PCB soldering, but Micro BGA shows voids more than 25%. Is there anybody can suggest for better solder profile. paste- aim m8, SAC 305, T4, Soaking (150-200) - tried 90s, 60s, 45s; TAL (>217)-

Hi Was wondering what the general take is with reflow profiles to take into account differing solder paste alloy compared to the solder alloy used for the bumps of a bga device. For instance, SAC305 solder paste and BGA device with SAC105 (higher m

We are in the process of launching a new product and found reflow solder issue with one of the inductors. I have set oven profile to paste specifications. I just finished profiling with thermocouple under problem component. All other components ex

Hello, I have a capacitor that doesn't form intermetallic joint with SAC 305 solder paste.The board is ENIG. Solder melts and forms good intermetallic joint with the PCB finish. However, capacitor can be removed with physical force - it looks like a

Thanks Dave, I actually found that article yesterday. It is one of the better ones out there. Unfortunately, though Ed does concede that there is a "sweet spot" in the process window for trying to reflow 01005's with SAC305 using air, no further inf

We have a PCB rework dilemma involving a reflow profile. This is a SAC305/Low Solids (aka no clean) process where we are currently hand soldering (5) components that were DNP. The boards have an acrylic coating and we take off the acrylic at the par
