I work for a small OEM. We have outsourced our SMT in the past and considering purchasing some used SMT equipment. My knowledge is limited in this area. Someone in my company has found a Zevatech 575 machine. Our run size is from 25pcs.to 500pcs.

Hi, How has it worked for you with small parts such as 0402, and are you using these size parts, and getting any tomb-stoning problems? We used lead paster with our vapor phase, while lead free should have less surface tension, so I have always won

Any opinion/spec/study on acceptability based on size and location of void in chip cap/res (e.g 0402) solder joints?

I know that there is no pre-defined strength for the solder joint as it will depend on solder volume deposited, pad geometry, lead component's lead solderability etc. but, what would be the best ball park for the good joint for 0402, 0603, 20 mil pti

1. We do have PCB with 0402 component, Micro BGA ( 0.5mm pitch , 0.25 mm pad size ). PCB thickness is 0.8mm. What stencil thickness we should use. PCB size 40 mm X 60 mm 2. We have EKRA E4 , What will be optimum setting for above. Pressure, Scquge s

for 0402's you should be able to run the turret at full speed, if you need to slow it down it means that your machine isn't set up properly. use the vision number that the manual tells you and make sure your feeders are properly calibrated, poorly c

Aperture reduction @ 5 mils thickness is your best bet. It may take several attempts to get just the right paste volume. What aperture reduction was specified to the stencil house for these specific LEDS? or was the stencil blindly produced using a

Russ, I tried to get a screen for glue but the design engineer who laid this board out made up his own rules. The 0402 pads are to close for a proper dot size.....per the stencil house. That is why I am going the solder mask route. I would rather

We have recently started building assemblies containing 0402 components (argggg!!). Were using the TM8FC magazines and are seeing alot of miss-picks on the 0402 components. When the feeder advances the part, the part can; jump out of the tape, or tur

If you want to use fuji CP6 machine, you have to buy the the fuji flexa software.Because the old software from fuji (MCS or F4G) they are not support anymore. In the flexa software you can make top and bottom side in the same program, you can move th
