Hello All, The audacity to yell Smartsonic here is appauling. This is a process approach dependent on the type of epoxy. To suggest your equipment without knowing a thing about the process is shameless. OK, now I'll get off my soap box. The low

Hi ZJJ, I know exactly where you're coming from on this one! We have a similar situation here with a SiPlace 80S-15, rated at 15K max per hour. In practice, we achieve about 11K. The reason is fairly straightforward. The quoted maximum placements pe

Instead of a Mnemonic, I used association to remember. The crazier the association, the easier it is to remember. And each person can come up with their own associations. Here's some of mine: Black - The room is black when there's no (0) lights o

Hi Greg, why don�t you see it this way: How many parts get lost ( consider the type and packing (reel, stick, tray ))loading the machine or replacing it. - This is the amount you should add for each job. How many parts are rejected or discarded by th
