There always are many questions relating to MLB's, and their constructions for laminate integrity, pad and material bond strength, dimensional stability, and electrical performance. Most often questions consist of those pertaining to board physical quality, effects of thermal stress during soldering and product operations, delamination (and related factors), warp and twist, "growth" or board "stretching/shrinkage," and what it takes to prevent defect.
Best Solder Tips BEST Instructors have put to video demonstrations of common hand soldering skills. These are not designed to be in place of live one on one training where repetitive skills and subsequent one on one feedback is given. Rather they are quick refreshers designed to be viewed if a specific skill has not been practiced in a while.

ScanINSPECT VPI Gives Production a Head Start ScanCAD International, Inc. Waiting until line changeover is finished not only delays detecting potential problems, it creates unplanned downtime that adds to production costs. That's the last thing any shop needs given today's competitive price-sensitive production environment
MYDATA announces first stencil-free solder paste printer MYDATA At this year�s Productronica trade show in Munich (A5:337), MYDATA automation will unveil its latest solution for flexible production. The MY500 jet printer is the SMT industry�s first stencil-free printer. This revolutionary new concept for applying solder paste to PCBs offers many advantages over the industry�s standard screen printer.
Depends on the actual requirements of the machine & the skill of the operator, but for that sort of money I've seen Juki 570's with a stack of feeders, Versatronics RV4's, older Mydata's, Samsung CP30's, Essemtec, Philips CSM's etc
You should not be worried about these points in the SMEMA standard. You need to make it work for your application. If you are running really small boards, keep the gap between conveyors and the lead-in as tight as you can.
We are experinecing adhesives left on the boards after running taped boards for placement verification on NPI. We've been using 3M double sided (333) tape for over 15 years. Any other suggestions on a good tape to use?
