Patrick, yes, the gentleman above is just one of the people involved in this RoHS nonsense, but I think the world reacts (or over-reacts) to individuals such as the one below:

A few good points have been made here: The profile could be ramping too fast. The profile could be gettting too hot. The profile may need to have more "soak" time before reflow to allow the board temperatue to equalize and the board to "relax" and st

Per our staff here at ACI......... Higher Temperatures maybe necessary to achieve good solder process results. The alloy formed when HASL coating protects the copper is the same as that when OSP provide protection. Temperatures may be increased to im

Hi Joane, this flux is primarily designed for wave soldering. I think that manual soldering it´s possible. Certainly it´s very hard to dispensing correct amount of the flux. Succinic acid is one from all ingredients of this flux. If you have this

Some print expiry date on reels and some specify a shelf life on data sheets. Two main reasons are that the flux in the wire is a mix of chemicals and over time in storage these can react so soldering performance can be changed. Although I have to sa

just out of curiousity, why the special nitrogen cabinet concerns for gold plated flex PCB? common "myth/fact" is gold is an "inert" coating layer that is not going to react with room environment conditions *that much?*. Am learning here, so would ap

Does anyone have any experience with any lead free solder paste and the "paste in hole " or intrusive reflow process? I am interested in how the lower "spread" of lead free paste reacts in a through hole soldering process.

What is the surface finish of the board ? Some flux are known to react with certain type of board chemistry. Have you verified the compatibility of your solder mask and flux ?

Unforunately, the only one who can give you that answer is the manufacturer. They are the only ones who know what is in their paste and how it reacts to different situations and conditions.

I'm not familiar with the HVN70 programming but our conceptronic oven reacts well to adjusting the cooling fan speed at the end of the oven. However, TAL will likely be affected substantially by changing fan speed.
