Troubles, troubles, troubles. If it weren�t for bad luck, I wouldn't no luck at all, eh? Tough business. Comments on your trouble are: * On machine vision errors from less than ideal capacitors: This is life. Reprogram your machine to either wid

Our SMTproduction has next troubles : 1. irregular 0603-components in tapes (different solder shapes) makes vision errors on placement devices 2. big solder amounts makes pickup and placing errors 3. some tapes delivery delays , so production halts f

I am haveing some trouble with ceramic capacitors breaking on a couple of boards I am running. The boards I have trouble with are in a 6 up and 12 up array and the caps are near the score lines where the individual boards are broken apart. Has anybod

I have come across a rash of failed assemblies that have 0805 capacitors and resistors, bottom side glued, wave soldered and washed. Trouble shooter reported touching up the solder joints on a few areas and the boards would pass test. I had a look a

Hi, I am looking for land patterns for 0612 and 0508 chip capacitors. Because they are not standard (yet) package sizes, i am having trouble finding a standard land pattern. (If you don't know what these are, picture a 1206 or an 0805 with the te

Howdy folks! Your friendly neighborhood SMTnet.com programmer here. I've spent the last couple of years adding features and fixing bugs for y'all, and now I need some help. The board attached to this post is an inverter for an LCD display fluoresc

Yes overrating in electronics is basically OK underrating , you are looking for trouble. sarason

do you mean the parts like capacitor or solder paste/solder bar. If you mean solder paste/solder bar, yes you'll have big trouble. Why? because LF solder paste/solder bar has high melting point and different composition. However if parts like capac

Yes, sorry I forget to mention it. SO only some capacitor will be lead-free. The rest remain 'Pb' parts. The solder paste also remain 'Pb'. You mean that if only this capacitor will change, we can solder that with no problem ? thanks ! habba
