I have used LTS (Sn57.6%Bi0.4%Ag) solder balls for soldering on Ni/Au pads, and I have observed a wrinkle pattern on the ball surface. When you attempted soldering on CuOSP substrate pads under the same conditions, the surface appeared normal. Additi

Actully none couse we glue them. Please see attached file - there are red dots marking glue placment. I understand you want to check if there is any sense in gluing components. I`ll ask one more time - Is anoyne who reworked SMDs with SAC305 where

Good day all, I wanted to get a quick poll from the folks running SAC305 in their selective soldering equipment. How are final results? How repeatable is the process, any machine related failures? pumps? nozzles? etc... I am just looking to get a

We are trying to use this high-temp solder paste due to a very special process, but we run into tombstones on chip caps, 0402 and 0603. We don't have this problem if we use regular SAC305 solder paste. If you have experience with this type of solde

Hi, we have an idea of running one side of PCB using 58Bi/42Sn solder to prevent glueing components on other side of PCB when board is on second run through SMT process. I wonder what issues we can meet once we try to use SAC305 when reworking some

Sorry new to this... Question: will I have any problem soldering a resistor network with SAC305 coated leads using a normal leaded wave process besides the normal board thickness issues Thx

Downhole solder suggestions, in order of preference are: * Kester Sn96.3Ag3.7. Most vendors do not stock straight tin-silver alloys, whose wallet is that fat? * SAC305 can usually be used in place of one of the copper-free tin-silver alloys in downho

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
