| Can someone please supply me with a footprint for a SOT 426-L, or at least point in me the direction of where I could find one. | | Clint two sources for ya: 1 Check with your component supplier 2 Use the following link Good luck Dave F

I have been asked to evaluate the use of and SOT-23-6. I guess that this part has been around for awhile, but I have never used one. It looks straight forward enough, but I was wondering if anyone out there in forum land has found any special issue

James, Could it be the convection in the reflow oven itself.Maybe somebody has increased the air flow or convection rate. I have seen an issue with an sot23 blowing off pad in a BTU paragon due to air flow in air curtains being too high. Hope this h

Are the pick up nozzles metal made (ironmagnetic material)? Some time magnetic residual on metal nozzles can generate pbm like that when chips terminations have nickel and when SOt or similar packages have terminal A42 alloy made. Time ago got pbm l

All, I continuosly have reliability issues when placing a SOT363 device. I have Fuji CP6 and CP4 placement machines. The part data has been analysed down to the finest detail but it is still hard to maintain any consistency. Anyone else have simi

Trying to electrical test some transistors SOT-23, SOT323, SC70 and keep getting the no value obatined? What would cause this everything seems correct in all the part data, etc. In the parameters we have the option :) pnp: mechanical phase (2) leve

If it's using the laser alignment try changing the part type to "SOT" instead of chip, and then enter the dimensions for only the body of the component. The "Chip" setting will measure the part half way down the body, the "SOT" setting will measure

I have a SMT-460 machine that works pretty good for the most part. When placing parts I have an issue with the SOT-23 rotation 90deg. Using both Juki 503 / 504 nozzle it will pick and place all of the 0805 and 1206 resistors/caps just fine. I have 9

Make sure your pick up and Placement theta are correct. SOT-23 are notorious for having bad theta data in part libraries. I had an old placement machine that would center the part with an upward camera, looking at the feet. If I had the wrong pick t

Another long shot. Are there any irregularities in the shape of the body or leads of the parts that are skewed? Any flash from the molding process for example? Almost all SOT-23s that I have seen are basically perfect but I seem to remember seeing so
