Wait a minute I thought I said Celestica and a few others have done the Engineering evaluations on a list of 10 top solder paste's and Indium SMQ92J and Kester's R560&562 came out on top. First you say 'don't trust all of the so called experts on thi

burguj, Please let me give you some incite to the problem that you have. This issue will depend on the version of Flexa that you are running. Since I am not sure of your name and company I will just say that if you are running the latest version t

Main difference is the reel holder position and for sure the clamping pin location. Tape feeding system is different. Any way they cannot be compatible among them. Q type feeders must be used for MV Q-Type placer and K-type feeders must be used for M
