Performing a wetting balance test would be very difficult. The flux cored wire "configuration" is just not compatible with the methodology of the wetting balance test. If the wetting balance is a must, then you might ask the vendor for the flux for

First, we don't know dip about nonbalanced squeegee. We clipped the above gif from: Solder Paste Printing Inspection: An Inside Look; E Litman, System Engineer, Orbotech; SMT January, 2004 Second, Tekscan talks about a product: I-Scan force and pre

From a process perspective, I don�t know if you should be concerned ... You've told us nothing about your process. THE BOOK JEDEC MO-51 allows 6 thou warp in smaller [1mm pitch] BGA and 8 thou in larger [ 1.27mm and 1.5mm pitch] BGA. The increase

Panasonic Factory Automation now has (or soon will) software to balance with other companies' machines. I don't know how it works yet, but is an option Lance I am studing the possibility of a line with one Siemens SIPLACE 80 F and a PANASONIC machi

Looking for Suppliers of surface mount wetting balance equipment. I've used Kester's equipment. It conforms to, and performs in accordance with requirements Dave stated. It's expensive stuff ($32K last time I bought one). For this reason, you migh

Greg, FYI, the concept of the Comet is that 1/2 of the board is populated on each table. This is in an effort to reduce the total transfer time hit per board. The on machine optimizer should be able to handle the split of the program. If you need

Hi.. Move the XY arm to the center of the machine. Turn on the servo then immediately hold “LOWER” then press “ORIGIN”. You should see the message now on the screen “DRIFT CHECK”. The arm will start to drift without an emergency condition occurr

I concur with your second approach. A profile needs to be tailored to the design of the board, the components, and the solder paste. Your first approach seems to try to balance lower quality soldering with a lower process complexity.

Re: CIMBridge, UNICAM, FabMaster, Circuit CAM, others?

We have 2 sites using CircuitCAM. It is very inexpensive (compared to balance). Uses straight gerber data (simple) and has excellent visual aids.
