I've done a few capacity and capability studies and bought new SMT equipment (Pick and Place) based on the above required capacity. I did not rely on equipment manufacturer's tact time. I used only 60% of their tact time as achievable in real manufac

Rick, You might want to consider a Quad 4000C. Even though Quad is out of business, parts and support are available from Precision Placement Machines. They are rebuilt with a warranty and run Windows 7. They offer intelligent feeders and if you don'

The my700 can dispense 1 million dots per hour. It's not an exaggeration either. It literally never stops moving, and is dispensing without contacting the board. It uses the same type of mathematical calculations that a plane dropping a bomb uses in

That does sound like a great deal Tsvetan. Can you share any information about who/where exactly you purchased the machines, and which printer/reflow you have? I do have friends and colleagues in China that could ease the process if anything is comin

From time to time, component suppliers decide to discontinue production of components that we use in our products. Occasionally, these components can be sourced elsewhere or designs adapted or altered to accommodate alternates. In many cases, however

Wait a minute...Your peak temps are PbFree like. Why is your profiler looking at time above 183 ? What is the time above 217 ? I thought we were looking at time above 217 not 183.

Hi, What would also be important is the time above 217. 20 secs above 225 may be the same as 45 secs above 218 That 7 degres might just buy you enough to sweep the non lead free components through Has anyone tried 220 or 218 peak temp but at lo

Can anyone please share a document which details about the soldering defects if you have less or the excessive preheat time, soak time, peak temperature, time above liquidous (TAL)and cooling time. Appreciate your help in advance.

First thing that comes to mind is that your �dip & look� testing at 240�C clearly doesn�t represent the in-use application of 215�C. So, what are the test results at 215�C? Other questions are: * Can we assume that the solderability of other compon

Krish, Looks like your peak temperature is around 230C and time above 183C is about 120-150 seconds. This is excessive for a leaded BGA. You should be aiming at 200 - 215C as the peak joint temperature with time above 183C of 60 -90 seconds. The p
