Hi, I always find difficulties of getting the SMD package dimensions as per the package type. Could there be a library which has all the SMD package drawings with dimensions? If yes where it is? If no what is the best way to procure such information

If you get the dummy components catalogs from Topline, http://www.topline.tv and Practical Components, http://www.practicalcomponents.com you will have most of the common SMD parts. There have been many inquires about a master list, or complete list

I have always encountered problems when using Kester (everything from bad solder to solder balls). I have profiled the boards to the extreme thinking it was my reflow recipie, but with no luck. I ended up going to AIM and I have never had a problem s

Indium Pb paste has always been great but the flux tends to implode on the BGA's (despite many different profile strategies). The Indium Pb-Free is horrible...horrible, and have been kicked out of my lead-free eval. PS-I went to Moonman/Guru link a

Hello! I suspect that our MPM AP25 has separation problems (poor stencil � PCB separation). I observe a lot of �dog ears� after print stroke. And this is 100% machine problem, I�m sure. What machine parts should I check first time to avoid separatio

Once again, it isn�t the process problem. It�s machine problem. I�ve tried to change all of the parameters: printing speed, printing pressure, snap-off speed, snap-off distance, etc. No any effect. Defect still exists with different process parameter

Yes, I agree, manual cleaning is not a solution, but does tell you you need to clean the stencil. You should have your stencil cleaner repaired and take that question mark away. Once all the question marks are goen you should be left with an answer

Good morning, Thank you for assistance. I�m not so experienced with MPM maintenance. Explain me please what is the difference between �squeegee down force� and �squeegee pressure�? Squeegee pressure is set so 5-6 Kg. How can I check squeegee down fo

Hello Well this is your lucky day, I would be glad to stop in russia on my way to california. And thanks rick I appreciate it. Would be glad to give him my e-mail, it is vmsales@alltel.net. Down force is very difficult to explain and MPM should no

we have two desk top XRFs and i would strongly recomend the desk top version over the hand held, its a lot more features and is more acurate. XRFs were mainly used for mesuring plating thiknesses before RoHS, and if your looking to use one most plati
