Cool! Might actually get that integrated into the SEC booster ,so choose a good register ;)

Which makes sense as you'd put the dip socket on that board instead, which also makes more sense from a reliability point of view with dips being less did say about bad connections.
The header pins on these things are so tiny and not easy to get to either. It be a lot easier to have normal header pins like the STFM boosters.

2 of these new STE ones are not working.. no idea why, but its like 50% failure rate so far :roll:
I'll add my 2 cents which canbe taken with a grain of salt. I've been doing embbeded software since there was such a thing. I have spent lots and lots of time trouble shooting hardware and I can assure you your much better off without sockets. All sockets are is a potential bad connection. I can't tell you how many times I ran into boards where the golden rule was to reseat all the chips. A few times of that and you have issues that continue to multiply. The milled pin dips are the only socket I have any confidence in. I have a st1040 with the 1.5 booster, 4 mb sim memory upgrade, and fast rom boards which are all soldered in. Thing is solid as a rock. In general sockets are just like drugs... just say NO. Socketed upgrades are easier to install but there not as reliable.

I take it you have not seen this post then ?

The first ste booster was solder in, because of socket issues... Problem is, most people destroyed their ste in the process... So I did a plug in booster which is the lesser of the 2 evils for people.

I did see it not to mention I had the similar experience with your glitter and socket converter that had extremely strong socket contact springiness. When I put that glitter in the board it did not work because I believe the glitter pins were compressed enough so they all didn't make contact with the weaker sockets I used on the board. Popped a glitter out of an mega and it worked fine. Never the less sockets are trouble!! As you point out. You should be commended for making the effort to have plug in enhancements for the soldering challenged among us although it makes the effort much more challenging. :thumbup: :thumbup:

After resoldering 3 boards, 2 seems to be working the 3rd doesn't.. I soldered all the parts other than the pins, I checked continuity and shorts, and seemed fine.. Even resoldering the header pins alone didn't work. But this reminds me of issues I had before where I thought something was bad on the PCB's somehow..

I will investigate more tomorrow (out all day today) though I don't get why these things have such a high failure rate. I may get 10 pcs done with a much large copper fill gap in case the CPU is shorting out to gnd even though it shouldn't be possible.. but 60+ pins and a tiny bit missing off the mask would be all it takes..

Its got to the point or considering the copperfill bending the PCB enough as it cools to break some joints somewhere.. Of make them iffy enough to meter fine but not actually work... Really hate these mysteries.. Has been a problem right from the start.. :roll:

Just remind me where you soldering with a heat gun or putting them in the oven? Just wondered if the heating and cooling program was too harsh and that's exactly what's happening?

These are done in the oven. Profile is as gentle as it can be.. Cooler settings and solder doesn't melt, hotter and it burns the PCB. Not much room for error between the 2 either :(

Reheating the board tends to fix them a lot of the time... Its like bad soldering but I never found any breaks anywhere. But these boards have been sat a few weeks since soldering. I'm thinking the board is bending during soldering, then when its cooled down, its under strain and over the weeks things break.

I'm going to see if I can use larger vias and tracks to them when I get back home... I've removed the bulk copper parts and spaced things out a lot more as well.
