Dear experts, We are in stage to fix lapse or hold time between pre-bake to reflow process ( SMT ) for flex-rigid PCB, usually for flex pcb , we need to assemble as early as possible once after baking & if not , we can store in humidifier up to some

Reflow Oven Exhaust

We're installing our first SMT line and my boss asked me a question I couldn't answer right off the top of my head. I have been an SMT process engineer for about 12 years and I guess this just never came up before. I was surprised but it made good se

BGA,s Storage

Electronics Forum | Tue Nov 13 19:58:28 EST 2001 | davef

No. I have never measured the temperature of the top of a BGA package during wave soldering. Mr. Kelly�s "actual body temperature" of 140-150�C during wave soldering is probably accurate [most of the time]. It�s the utility of this measurement tha

Nitrogen and dry cabinet

Electronics Forum | Tue Jul 30 08:38:55 EDT 2002 | dasal

Truthfully, there are pro's and con's for both technologies. (put cost of ownership aside for one moment) Nitrogen won't dry humidified components as rapidly as a desiccant dry box. I'm talking about a self regenerating dry box that uses molecular s

J-STD-001 Par 4.2.2 Temperature and Humidity

Electronics Forum | Mon Jul 16 15:44:27 EDT 2007 | davef

J-STD-001 doesn't necessarily require additional controls under conditions of low humidity, only that you verify the effectiveness of what you have in place. ESD S20.20 [1999] only says that relative humidity above 30% is "desirable". ESD S20.20 [200

J-STD-001 Par 4.2.2 Temperature and Humidity

Re: adhesive for ptfe boards

Electronics Forum | Tue Oct 05 04:23:38 EDT 1999 | Brian

Can someone suggest what material I have to use to protect components by electrical discharge on ptfe based boards? It should have high resistivity, thermal stability (-40 +70 'C),perfect adherence on ptfe... Many tahnks

Cleanroom Basics

Electronics Forum | Fri Jun 24 08:47:14 EDT 2005 | grantp

Hi, There are many aspects to consider. 1. Firstly the room needs to be designed so it's sealed, so linoleum floors than curve where the wall meets the floor, so dirt does not get trapped in the corners, and mops get all dirt and pick it up. Floor
