I'm considering using Delmat, or some equivalent material, as a stiffener for rather large pcb, but I don't know the material properties. Specifically I'm interested in: Young's Modulus, E Poisson Ratio, nu Density, rho Strength, Thanks, Jim

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

Sounds like someone aimin� fo tha big hurt, if ya axes me. Two spots to place your lawn darts are: 1 J Hwang in "Modern Solder Technology � " states (p.354) that " � extreme CTE mismatch between silicon IC (~2) and the PCB (~16), solder connections

Dave, Firstly..how the heck are you?..been a while.... Ok so I'm running an Electrovert Electra witha hot gas knife, & I've got large server boards going over the wave. I've seen us loose chip, mainly Tants on the hot gas knife...ain't good especia

Mike, I understand your dilemma very well. You see, I was a manufacturing engineer for 11 years doing make or buy decisions before getting into the sales field. But for this commentary I will wear my engineer hat. Your situation is not uncommon.
