The CSM84 I have is 63" (1600 mm) wide, 57" (1450 mm) deep, and 54" (1372 mm) high, without the turret. The CSM84 is rated at something like 1600 Lbs (728 kg). I had to cut a hole and install double doors to get mine in. I can't imagine "carrying" t

We have been producing an IMS assembly with SMT dpak's for some time. However, we recently encountered a new problem by chance - the parts can be flicked off with a finger nail. I state by chance because the solder joints are wetted and shiny with

A keypad overlay is used to adapt one basic keypad design to a variety of applications. The overlay is positioned on top of the key board to match functions on the overlay with buttons on the keypad. The user selects a function on the by pressing t

The proper method is to load a flat plate into the X-Y-Z table. The plate size should be as large as the largest board you run. Indicate the entire area of the plate with a dial indicator. I don't remember the exact spec, but try to stay within .2mm.

We seem to have an overwhelming amount of foam produced in the initial rinse portion of our wash (enough to cause it to overflow). We are using an Austin American Hydrojet Mach III Inline Cleaner. To my understanding the first rinse of the boards is

The presence of agitation at an air / solution interface and a foaming agent causes foaming. Most water soluable fluxes contain surficants. Surficants are foaming agents. First, it's likely this foaming is caused by poor control of the temperature o

Brian, We had similar problem in our inline wash machine time ago. We checked everythin on equipment (filters, DI water purity, sprayers angle, etc). To make the long story short, we found out that the problem was caused by a new solder paste. This s

Brian, We've see foaming issues with our wave flux occasionally when running large slugs of product through the wash. We love the wave flux and changing it was not an option. Our process parameters for the wash machine we're derived via a validati

Most often, when people talk about a dishwasher, here on SMTnet, they're talking about a batch cleaner, not a dishwasher from Sears, or someplace like that. For limited applications, a home use dishwasher will do a perfectly adequate job of cleaning

We use an older industrial dish washer to clean our boards, and it works out pretty well. Economical, at least. I'd like to upgrade to an in-line, but it's not in the budget, yet. We've got ours piped with de-ionized water, and a hot water heater
