We evaluated (in-house) 3 Paste Inspection Machines: 1.Siemens 2.Agilent 3.Cyberoptics We also evaluated the MVP and Orbotech off-site. BY far, the CyberOptics machine performed the best. Gage R&R was remarkable, the s/w is second-to-none, pricing

Folks, I work in Supply Chain and was wondering if anyone in this forum knows a website where I could find recent market information such as industry average price for the major solder products such as lead free and tin lead bar and paste. With the r

Talking about lead-free idiocy. Here�s the result of what you get for being GREEN and paying trough the roof. Since the implementation of lead-free I don�t buy green shirts any more, because they charge me twice as much as the blue ones On the positi

I am not a big believer in these systems, unless you are doing a no-clean, multi-shift operation with minimum changeover. If you are a small batch shop, the amount of solder paste you end up wasting can actually be the same or more, if you are not r

Well, we are in fact doing a no-clean, multi-shift, very high volume, minimal changeover operation. We use up any paste long before it gets old. Because of the sheer volume any reduction in paste scrap for us is big money. We also are in a zero de

I am printing a ceramic paste through a 160 mesh screen that should have a theoretical wet print thickness of 53um but the only way I can get the print that thin is to increase down stop and slow the stroke. This is causing problems with the mesh, s

Hi, We use the standard pin supports when necessary. Are your boards very thin i.e less than 1.6mm ? or maybe panelised ? Other things to check are Z0 placement height aswell as damaged nozzles,sticky nozzle/nozzle head , poor feeders along with t

I don't know of any standard, but do know most suppliers will sell you sub-par displays. Inner layer cracking is usually the biggest defect due to handling. We had our supplier in and they showed us what to look for under magnification @400 times.

Sure you can. But I don't have the time, money or resourses to do this. I do not have the luxery of only getting SnPb parts. Wish I did, but I don't. As for temp specs, I know the specs on all my parts. We profile our ovens every month. We can

Sr. Tech I thought that was you, and have been wondering how you was doing. Any one that has been around this pcb business, if there is a business any more, knows that we all get involved in dealings that we could have done different. I do have a f
