This is what�s going on over the pond. The request to exempt the lead in electronics on environmental grounds, filed by the courageous fellow lead-free rebel John Burke (RoHSUSA) has been accepted for review by the EU TAC. http://ec.europa.eu/enviro

Hi, where can I find info about how to make the pad design to work for VSSOP48 0.4 mm Pitch & TSSOP56 0.5 mm pitch components? I should also mention that we are working in a project that this 14 layers High-Frequency RoHS board is included. The pad c

We're not real clear on the issue. [Got ourselves wrapped around lead (Pb) versus lead (termination), we think.] That aside, comments are: * Boiling point of lead [Pb] is [/K]: 2022 [or 1749 �C (3180 �F)] * It's possible that the material that com

>>> Now you must take into account your total board mass as well. If you have tons of heat sinks, or parts on the other side that can affect your profile, you should have them on the board when profiling. That�s where the "engineering" part in all

We have fought with cut-tape way too much. It's always a bad idea. We've tried a couple methods/devices for manual splice with limited success. Before you look into this I would ask them if they could supply you cut tape qty's inslusive of fairly

We build quite a few cables ourselves, and we go through a lot of heat shrink labels. Unfortunately, we only use Brady heat shrink labels, so I don't know if I can help much. Are you actually running raw heat shrink through your printer? If so, go

I would concur with the above comments. We have used Juki/Zevatech from the 570L model on and run a full complement of 700 series machines. I have a 10 year old 730 machine that still cranks out product every day over two shifts without problems. Yo

Thoughts are: * Eliminate solder spotting on gold fingers through process improvement in broard handling, printing paste control, and reflow recipe development. Search the fine SMTnet Archives for previous discussions. * Dispense or print a reflow te

All, We have ran a few revisions of a New Product which is a tracking device using satellite navigation. The protos went well but now they have added a shielding can. We place 2 of these to cover the Frontend of the PCB. The test guys are having d
