The program that I use is the Fuji calibration program and it works fine on all other equipment that I use it on. The PDs are dialed in at 10% tolerance and the nozzles are new. I see it more on 105 and 1608 parts but it happens on 2012 and 3216 part

SAC 305 liquidus is 219 C. A hybrid profile is often recommended with a peak of 230 C (reflow the SAC and not kill the Pb parts) with an extended liquidus of 60-90 sec to get good alloy diffusion. Or if the design (parts & pwb) can tolerate it go P

Thanks Bob, I will change the z-rod just to make sure. It is a tall part read at 180. The nozzle height bugs me because we have 3 machines and the first one has a nozzle height of 238 while the 2 others around 200. I am thinking this parameter may ad

Biggest problem with the IIF is placing components with varying thickness (i.e. multpile vendors). We have to adjust production programs at start of each run to prevent excess scrap. Line Sensor tolerances can be adjusted to accept a wider range of

Hi, Are we talking about the pick-up tolerance so for any chip component set it to 0.5mm. It will save a lot of trouble right there. As for body tolerence if it is a zero then it will automatically use a standard value, based on the size of the body
