Hi Prem, OK... Is it definitely ok before the oven, as it's a big part to move. Never had an issue with them. Has the part got the correct z height on or is the paste being displaced on placement What machine are you placing it with (is it laser

Hello Mika, I just checked a windmill and a test nozzle we have on the bench. The useful travel of the nozzle before the risk of the crosspin getting stuck in the loading gate is 1.5mm, if it gets stuck it is the nozzle is 1.7 up. If the cross pin is

Hi Mika, I used to work for the largest chip cap manufacturer in the world, and by far the largest problem we would see was cracking due to incorrect z height adjustment on Chipshooters. It can also cause solderballs and bad joints by displacing th

Thanks all for Your input. The thing is that we want to avoid to go in to the pattern program and change the height in the middle of running a board. For ex. We start a product, feeders are loaded in advance in the feeder preparation area, operator

Difference in pick height from paper and embossed reel (typically) is 0.2 mm. Try to change your pick height and place height (different type of capacitors have a different height: for 100 nF 0603 and for 4.7 uF 0603 it's a big difference!). Can you

0201 Feeders are a different height than regular 8X2's I have put them on a surface plate and measured them with a height gauge. FYI: They make 0201C (Capacitor) and 0201R (Resistor)Again the difference between the two is height. Also it is CRITI

Hi, Noticed that MPN--MAL215099913E3 used in one of our assembly with 22mm component height. In General 15mm height is right to set height calibration (98 % of the parts will be covered with this height dimensions except specific Connectors, Transfor

I agree w/ JB; the package height definition is crucial. I have had problems w/ this in the past, and found that a resistor height was being used as a universal passive height for the capacitor in question. Properly defining the height fixed the pro

Hi everyone, One of our customer is asking us wich one of these two components has a better resistance to vibration. Vibration can be a potential problem for them. He has the choice between a thru hole radial capacitor with near 0.400 in diameter an

For space contracts we have to mount chip capacitors/ resistors etc 0.1 to 0.4 mm from the pad height. This is to compenstae for the CTE differential in the substrate/component and also to ensure cleanliness. Does anyone have any new ideas on how t
