And yeah figuring 30 to 45 mins of smt rework per module if i get a good reflow on said chip. That’s not even counting my time doing QC on my batches. Don’t get me wrong I’m want to sell my products a good price for everyone, but until I can figure out how to use Taobao and try to get my cost down, I kinda have to stick to my prices atm. Next your gonna say a switch usbc port replacement for 45$ is expensive as Fudge bc it only cost me $1.78 for an replacement port but who cares about the time it takes me to get it prepped, reflowed verified working then reclean it.And for ordering at bulk prices, cost bulk cash and I personally don’t have 15k~25k just laying around to invest in ics from China that could possibly have fake capacity. And honestly price double over cost is actually a very cheap markup vs regular store markup and seeing how there isn’t any competition with different prices I have nothing to base my prices off other then my cost and how valuable I consider my time.
