Hi Eric, Every mounter have a standard count and "release" off the component. The sample and cost saving way is to use the paper (e.g: 4mil,5mil...thick) to measure. Just place on the PCB with supoort base below and release the nozzle step by

Sometimes solder balling is related to oxidized paste or paste that has sat on the pcb too long before reflow. Mostly it is related to process, sorry... Too slow or too fast of a reflow ramp rate. Heating up an assembly too quickly will not allow the

SMTRESEARCH.com has an excellent machine POD. I have yet to get a demo on it but the litature looks great that they sent me. We are using fujis DT651 which is good a machine. It isn't as user friendly to decipher the results for machine faults as th

Have been through this before and we resolved our problem as follows: 1.Make sure that the length of your board support pins on Your HSP is correct. On that machine the board support pins depends on the board thickness (+ - some tenth's of a mm). It'

First, Your flux is no good replace it. second, Check for pre- oxides. The smaller the component or the leads makes it difficult to solder specially if it has oxide. Thrid, check the board to wave parallelism. Maybe your wave is not parallel to the b

I have seen some crazy placement problems that I just couldn't figure out in the past and several have come down to boards moving in the clamp. I would double check to make sure you are clamping secure enough and slow your table speed down and see if

There is a couple of things to check. Put the machine in diagnostics and let the chain run. You should see it run the same as you would if purging it. Sometimes the 2 hall effects at the disk do not see the disk as it turns. Check the driver board

The only time I have seen any Fuji IP need calibration is if you have had a serious crash, or if an axis or camera has been removed. Make sure you don't have something else going on. For instance check these things: 1.Check nozzle vacuum 2.Make sur

I am using this same flux and haven't had too many problems. I think Russ is steering you right on your wave flow and I would also check the fluxer performance to make sure it's getting to the top of your board. Are you sure these aren't sunken joint
