[Ovmsdev] Fasttech production problems?

My unit is intermittently faulty (almost certainly a dry joint by the
sound of it) but as the supplier I bought it from no longer sell OVMS
then don't seem to have any interest helping out. I may simply buy a
new module, but am waiting to see when reliability improves.

> Dry soldering is about the only issue we've ever seen in any numbers over the years. It is frustrating because we group the batch sizes up (making hundreds of modules at a time) so that we have enough quantity for machine soldering, but still the quality sometimes is not there. The 'fix' is normally 15 seconds under a hot air re-work station.

>> "More" is relative -- there was one guy whose module had no GPS a few weeks ago, and I just had some headache diagnosing a module that got stuck every once in a while on CAN writes -- I told him to check for bad contacts and he found a poor soldering point at the CAN transceiver and fixed it himself.

>>> Fasttech is just the distribution point - they don't deal with the manufacturer. We've used the same module manufacturer since the v2 hardware was first released, and are very happy with them.
>>> We're currently out of stock of modules, and have a new batch in production. It takes a little longer than normal at this time of year, due to the Chinese New Year holidays. Our manufacturer is fine, but things like the PCBs are sub-contracted out and these sub-contractors are busy. The modules should be back in stock within the next 7 to 10 days.
>>> We're also currently out of stock of lefty OBDII cables. A year or so ago, we identified a manufacturer for cables that we really like dealing with. At that time, we tendered out to half a dozen factories, and the one we eventually chose came back quickly and efficiently with a very reasonable price (not the cheapest, but the most professional and reliable). Since then, we've used them repeatedly, and every time they do the job very well. The order has gone in, and the lefty cables should be back in stock within the next 7 days.
>>> Regarding hardware failures, I've had one RMA replacement last week - but that has been the only one for months. I think there were 3 replacements in total last year. That said, I think people like Pierre are handling some repairs locally for us, and I don't get to know about those. But, from my point of view, I'm really happy with the current hardware reliability, and no big issues found.
>>> Gotta say that most reports of hardware failure end up to be a username/password typed incorrectly, or SIM balance too low. The FAQ I put up on www.openvehicles.com helps tremendously with that (as it forces people to check each parameter, like a check-list, and most notice the mistake then and there).
