You have a resume posted 5/6/10 that's actually an advertisment. Jerry

The one i've been using on some thermally diverse boards with great success has been henkel loctite mfr 301. It's alcohol based not quite the solids you are looking for but close it's 5.5-6.5 solids and it is no clean.

IPC-A-610D refers to 'toe down configuration' several times, beyond the 8.2.5.6 that you question. Although none will add to your understanding of 'toe down'. A lead that is 'toe down' is one where the foot of the lead is not parallel to the pad. T

Toe down solution: * Land pattern design * Solder stencil design * Proper component fabrication Normal gull wing lead solder requirement: Solder must extend to the mid-point of the outside of the lead bend.

If the solder joint meeting 8.2.5.4, minimum side joint length(D) and also meeting 8.2.5.6, minimum heel fillet height (F) but the heel fillet NOT extend to the mid point of outside bend. It is acceptable?

We'd say yes, if it meets both 8.2.5.4 and 8.2.5.6

kumar, can you explain why in zones 5, 6 and 7 you use different temperature on upper and lower heaters? Do you use a Nitrogen in your reflow oven?
