With all said I would still avoid place them under tall or sensitive parts. Still follow common sense.

I have a recent design (1 component side only) that calls for 2 surface mounted antenna's (brass plated) to be mounted on a PCB. The problem arises when the PCB is 18x11.25 and has 15 to 20 PCB's in the pallet (IE weight, fixturing to hold the anten

I have some BGAs with a warped chip carrier. Some of the balls are tall like columns and some are short oval shapes. How can I determine when warpage will cuase failures from stress. Is there a spec out there from studies anyone has done? Any commen

If I did the math correctly, we're talking about over 600 BGAs to rework. I have nothing of relevance to add other than Chrissie should be given a medal for not jumping off a bridge or tall building. Let's save that fate for the operators who didn'

Hmm..that gets me thinking. How about lightning rods for SMT equuipment. Actual conversation of customer on plant tour: Customer: "What the hell is that? Is that a 30 foot tall signal tower on that stencil printer?" No. That's our new speedline

Your inspection people will tell you what they need. We have some that prefer to stand while others sit. It has to do with chair / table / operator heights. e.g. tall table with a short operator they will want/need to stand and vice versa. Usuall

Rick, you have not heard everything, I believe Fuji is rating thier machines by cubic footage. I guess thats to keep the competition from making 9 foot tall placement machines. Gee, didnt someone try that with ovens a while back? I would still love

Are you setting up double side PCB that has the tall components on the bottom that being push up by the support pins... ??? Or because your vacuum is leak and not holding the board at the same spot every time you are loading the board.... Board warp

How big is the cap ? We successfully reflow caps that measure aprrox .750" x 750" at the base and are .678" tall. The ovens we use are Vitronics XPM's.(1230,1040 and 930) We also process these caps through our Omniflow 10. As stated, oven length wi
