1) I think maybe not, however having said that, our conveyor does not work between the final placement machine and the oven, in the early days before I became a "experienced" operator in pulling the board out of machine running it along the track to

Upside down placement of a crystal oscillator is acceptable or not ?? As per IPC 8.3.2.9.2 Rectangular or Square End Chip Components – 1, 3 or 5 Side Terminations.I am not sure whether is applicable for crystal oscillator or not . Your answer wo

Thanks mike .. it would really helpful for me

What kind of oscillator are you placing (Manufacturer part #)? I do not believe that oscillators fall under the "chip component" category. Even if they did, most all SMT oscillators that I have come into contact with have 1 sided terminations on the

So, to really get reliable pickup rates from new bulk feeders, I just need to replace all the chip shooters we have with more recent ones with pickup correction capability. So where is the saving? ;-) -Upside down resistors? not an issue. so what if

This will probably sound like a dumb question, but... I have a specific 1206 chip resistor that routinely ends up placed upside down on the pcb. We use Juki 750 placement machines. I normally run the machine with the auto-correct for the pick posi

Sal, Interesting problem, I have found that W.S. pastes tend to have a shorter tack time in real life than what is advertised. Usually the manufacturers specify tack time as after placement let the board sit and then turn it upside down and see if

In a perfect world, the machines would be maint."guys" for the automation machines. Think "closed loop" system. Anyway, getting back to our reality job, we are still game for automation to improve thru'put, quality, reduce problems. The focus here

Hi, We are currently working on a board that has 3x 50-pin THT at 1.27mm pitch each. This is too small for us to be able to consistently do on our selective solder. We are instead considering pin in paste. The connector we are using can be spec'd at
