You may also wish to check the speed controllers for both descent and ascent. The higher the ascent speed the more force the jaws close with. It can be difficult to achieve a "good" nozzle placement height as this is mechanically set and your lowest

Are you saying you can't send out boards that have been touched up or reworked, or are you saying you can't send out boards with defects on them? 100% is a great goal to shoot for but most people don't expect to achieve it. It all depends on what yo

We need more information about the situation. For instance: * Describe the green residue * Talk about the distribution of the problem, including a single lot or from various lots and over components and component types on the board * Tell us about t

I am sort of familiar with Specnor Tecnic myself from work at a previous employer. Yes, they are a group that split of from Electrovert and actually compete with Electrovert in their spares market. Don't know how that's legal but they seem to be doin

"find yourself a good stencil manufacturer its there job really just tell them what machine you have and they should do the rest." I have to dissagree with this last statement on so many levels. There's a reason why it's called engineering. Plus,

Aperatures are often best decided by the stencil manufacturer principally because they would know what is easiest and best for there laser cutting machines, why would i dictate to them something that would not work well for there machines. but are yo

Also we have just made a prototype for Wave soldered SMT components D-packs + 0603 + TSSOP�s on the bottom side with THT comp. on the top, the stencil manufacturer gave his personal library of glue stencil openings and adviced on stencil thickness wh

If you mention mis-alignment and missing component in the same sentance, I suspect the component is not properly released after placement. Assuming the Juki machines use an air blow, after vacuum shut off, than I would look at a correct air flow firs

thank you devef....My point is this....If you solder all the areas that have Imm Sn on them, there wont be any whisker formation DUE TO THE IMM TIN COATING.....whiskers could still potentially form as a result of COMPONENT FINISHES and effective miti

If you are happy with DEK I would stick with that. I'd look at an ELA or a Horizon model 03...which is their stripped down Horizon version. You can buy a new one of those in the $60K range...used obviously less. The only other vendor I would look a
