Hi everyone, this is my first time on this forum. I've only been an innocent bystander. Until now. I wonder if anyone out there knows of any technical publication (accessible over the net) that explains, in detail, the actual physics involved regardi

Hi Jason! I can probably find something documented for you, but the easiest way to convince your QA people is just to show them. If you have a board around that has some 1206 locations all in a row, print the board with paste and then plac

1.Can anyone explain to me what is the clean and non clean solder? 2.What is the standard solder paste height spec for stencils 4mils,5mils and 6mils? 3.Whatis the meaning for ROHS?

Q1 Can anyone explain to me what is the clean and non clean solder? A1 The trend away from CFCs has lead many users to evaluate switching to no-clean soldering processes. The term "no-clean" is actually a common misnomer when used to describe a flux

this would be meaniung that somewhere in your documantation it should have spec called "repeatability" what this means is that when the vision aligns the stencil/board, the board will always be within "x" amount of the njominal xy "T" position, some

Hi Steve-O, Good question(s). This process was set-up by an engineer that had a PhD in statistics, took him a year to develop and then thru it over the wall at us. The biggest problem we saw was SPC to measure solder volume. SPC is good for measu

Hi All, Just have a share with you guy. We are using T4 solder paste and also E-Stencil. We ahd try out Alpha, Kester, AIM and Qualitek. The result show Alpha had a very very heavy stack flux and can't get it clean off even by chemical

If it's really low volume I would only invest in a stencil printer and convection reflow oven to start with. If you want to go really low budget get a manual unit such at one from Transition Automation. Make up some really good shop aids and have s

What is your alignment method for printing? Vision? Mechanical? What is the advertised repeatability for your machine? Russ
