celldude, I have a couple more questions for you. Where can one look into getting these machines necessary for SSD? Also, knowing that the machines are expensive..Does your company find they are saving money (in the long run) by using SSD? More spec

Stefan, The scenario you describe is the way it is done on our 3 series placement machines. The C5 series is a databased arrangement. Each reel (tube and tray) that comes in the door gets a unique ID (and a barcode label). This is done with the C5

JB, First of all thank you for the "great salesman" compliment. And thank you for bringing up this wonderful thread because the more people that read it the better. I don't mean to make you look foolish (or maybe I do) but perhaps you should take a

The alloy I have chosen uses a wetting angle of 50-70 degrees. Different alloys have different properties. I coupled experimental data with what others have published. Nothing new here. As for reliability...I think you'll be surprised what lead fr

Adam, I would first check hole to lead sizes on the components that you are having hole fill issues with to see that the spacing is withing spec. Second, check for oxides on lead tips, and contaminated leads that cause poor wetting and insufficient

Hi Arvydas, Do you want a machine specified at 20K per hour or to run at 20K per hour? Regarding Chipshooters I've worked with Siemens, Philips FCM's, Fuji's, Panasonics & Sanyo/Universal and the best in terms of reliabilty by a long way were the J

Pb free pastes do not wet out like 63/37. Their are no claims from any manufacturers that I am aware of that say it will. Your "little solder balls" are likely caused from oxidization during reflow. What type paste are you using 3,4,5? What are t

What config are you replacing? ie 1 machine, 2 x 3machine lines, 1 x 2 machine line etc. What do you want to place with it? I can't comment on the Contact machines having never used one. On Samsungs I will say this. For your own benefit consider the

It all depends where the voids are, and that's tough to do with a transmission x-ray. One needs to be able tilt the assembly at 45-degrees during x-ray, so you can get an idea where the void is. Or, you spend some big bucks for an x-ray laminography
