Greg, The operating parameters for Wave Soldering are: 1. Preheat Temp. (80-110 c, board surface); 2. 1.5-3 secs dwell time in solder. This, 1.5 second, is the time required for both the lead and solder to gain sufficient heat and as a result "tinn

You're entirely correct. The gold is most likely gone away. [Don't forget you can check if the surface is still solderable with a hand soldering iron.] We're not sure it it will give you the results you seek, but consider using a dye penetrant fai

This is my first circuit board that I am attempting to build and need a little help. Not exactly sure what is going on but maybe one of you guys could give some input. I am attaching the electrical diagram I am using. Everything thing seems to be wor

Mark, A challenge for sure. I suggest you review two techniques for this type of rework\modification. The first method uses a special circuit track run out from under the BGA. See: Jumper Wires, BGA Components, Circuit, Track Method at http://www

I'm using Kic Profiler and aluminium tape from Kic and thermocouples from Kic. They are good and reliable. I even manage to modify my heller 1088 by adjusting the fix conveyor and re-baffling the oven. Had dropped my 20-22 deg. C delta T down to 4.3

You bet our reponse changes. Q2R: Hard gold thickness is 4 to 10 u" for Au and 300 to 400 u" for nickel A2R: This is a hard gold spec?? It looks like a ENIG spec. Although, the Ni is quite heavy, 150 uin is sufficient for most applications. The gol

Hi Gavin, Depends on what MSD class, but in general for the more sensitive parts if they've been opened & not used within the time limit it's rebake, add dessicant & seal. Our distribution side splits them down into more manageable/production size

Roland It's nice that Peter is considering improving the site. Things we'd like to see improved on SMTnet.com are: * SEARCH that works effectively. [We can't find postings that we've made. AND we know the key words. So, it must be painful for oth
