The 7 spindle Flex jet head, can only pick max 7 comps. from the GSM base machine in a single operation, not from the shuttle. The Flex jet head is faster in z-axis and will also use the OTHC (On The Head Camera) to inspect most of Your smaller comps

Jim, you may need to look with different paste instead of the cleaning solvent. Please advise what is the paste which you currently using? Beside, when you talking about the board stayed in hot area, is it a drying area or the cleaning zone. If it

Prasad, It is typical when experimenting with new materials to have to adjust the airpressure on the syringe and the stroke of the PDP piston (screw adjust on top of the PDP pump). You can add mutiple cycles in the comp Db to make larger dots with th

Thanks for your reply. I 've tried to clarify and answer your questions. The water soluble paste used is WS3060, type 4. The boards are sent through a inline di cleaner after reflow. There is a hot Di waterwash, rinse and then hot air to dry the wa

We have an assembly that requires a number of high density connectors to be placed after SMD. The process will not allow a normal wave solder setup due to the population of SMD comps. We cannot use a selective solder pallet due to profiles. We are

yes, it could have been from all 3 locations. without any detail whatsoever about your process or anythign it is impossible to help!! please check your incoming material prior to processing please check your reflow profile to ensure that max temp

My company currently uses water soluble paste for our SMT process. We were having trouble retaining hot water in our in line, closed loop DI cleaner. The cleaner kept shutting down when the water temp. dropped below 125C. As a result, the conveyor

Curious, very curious ... Residues � Where are these residues? [solder & laminate / mask, solder only, laminate / mask only] What is the result of your analysis to the residues? How do you know it�s a flux residue, rather than a chemical by product

| OK, my manager read an article on printing glue (aaargghh!)and wants to know why we aren't doing it. We currently use Fuji GLs and GDMs to dispense glue. I've never done it, but have seen it done at NEPCON and other shows. It looks OK, BUT what
