Hi Ivan, J-STD-001C chapter 3.6.2 says temperature should be maintained between 18�C and 30�C and humidity should not exceed 70% and below 30% verification of electrostatic discharge control is advised. This is a wide range and I wouldn�t allow a sw

1) I had downloaded ANSI/ESD-S20.20-1999 from www.eosesd.org web site. I am not clear whether section 6.2.3.2 is correct. It states that " All process essential insulators that have electrostatic fields that exceed 2000 volts should be kept at a mi

Hi, I take it you are refering to intrusive reflow? It came around as more components became available in surface mount packages leaving mainly connectors left over for a separate insertion operation & wave/selective/hand solder. Manufacturers imp

What operating system are you using ? I have found that you need to stay with a DOS based operating system. I am running DOS 6.2 with windows 3.11. I tried win 98 and although it seemed to run properly, I would have problems in the final program. XP

You cannot determine foil thickness from its weight per area, because of the significant variation in the density of electrodeposited [ED] copper. But people don't care. They do it regardless. (oz/ft2)||(mils)||(mm) 1/2||0.7||17.8 1||1.4||35.6 2||2

If this code is on a ceramic cap then it is a 0.1uf cap. We have a conversion charts that list most all codes. Useing the last 2 digets only determine the value. The capatol letters A thru Z are given specfic numerical value. Example A0 is 1.0pf, A1

Alberto: There's no rules, but it works sorta like this: RESISTORS Usually marked in ohms using a standard code: First two numbers is the value Third number is the multiplier 102 = 1.0 x 10� ohm = 1000 ohm = 1 kW CAPACITOR Usually not marked. When
