It seems familiar, but nothing that I've actually experienced. I've read some articles about tin-whiskering in lead-free solder. I think NASA has some pretty good analysis (or, at least they did a couple of years ago). The summary is that without

Early on when we started looking at BGAs we tried dipping. We've done it in production for a couple decades with flipchips. Dip fluxing BGAs worked fine in the lab but we ended up starting production with screen printed flux for cycle time reasons.

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

The issue is not with the stencil cleaner, it is with the construction of the fiducial. Ultrasonics is very effective in cleaning and penetrating into small microscopic cracks and crevices (this is one reason why ultrasonic stencil cleaners are so

I know of a machine that has: - 54 8mm slots - Single up JEDEC tray holder - And the availability to present tube parts without taking feeder slots. This product has full vision and can pick and place 0201 components and "fine" pitch to .020". With

Size is absolutely no problem for us, and neither is the need for 3ph. power. I've been shying away from the Universal GSMs because it appears their feeders can only index a certain distance which sounds like a real hassle. Also, I'm not too keen on

Hi Jeff I would recommend you to try unexpensive user friendly Juki Late Model KE760 series. you need a flexible machine that can handle components,fine pitch QFP. This machine is very unique. you can use even without an offline software optimizer,

Hello, Mydata p&p machines are built for high mixed and low/mid volume production, so if you talk about very low volume - no doubt, mydata is what you can use. You can consider 2 models for your application - MY100SX or MY100LX, depending on the min

I am having some problems getting the IP1 to place a SSOP28 package,pitch 0.65mm lead width 0.3mm. I am selecting computer vision 012 (tried 011) and vision type 100. EL data was put in looking at the datasheet and also measuring the device. Have tri

Hello mickd, 1) The EL data & Vision_type is NOT necessary when using MCS30 for IP1 machine. note : your input of the above might have cause confusion during VP, hence the OS error. 2) I would suggest the following... 2a) lower the Lead_check_are
