Sorry about the long delay. Thanks for your honest opinion. I've decided to hand solder the batch of mechanical relay boards. It took me a lot of time and effort against an aggressive deadline but I managed to finish. I have a few reasons for making them myself:
- The time line was extremely short. There's no way to get contract manufacturing done
- I have to flash firmware, run function checks, fix boards anyway
- I was able to find how how many boards I can build within what time frame. I think it's an important part of my business because a client either wants me to make boards or wants me to contract the boards to be made by others. I need to know which option has what kind of time line.
With future batches of comparable or larger quantities, I'm going for a regional contract manufacturer for quotes so I have some ideas of cost and time line.
