Corporations have sold America out for cheap Chinese production from Furniture to Microchips.You do not think these companies are designing their own circuits, scale/load cell, motors then having them built to specification?? They are at best having a designer design the external plastic shapes but the rest is off the shelf parts built in China or outsourced by China!!! LOL How many electronic circuit designers do you think these companies keep on staff? LOL.....It is not like General Motors were they have thousands of Engineers on staff year round and hundreds of contract engineers, chemist, designers etc......More than likely all the engineering and designing is likely on staff at the factory in China were these are made. I deal with China, Taiwan and Eastern Europe routinely for manufacturing. Fantastic people to deal with if you are not looking for the "cheapest" no questions asked widget you can get away with selling that will not destroy your companies reputation. You have to represent your company well though, ask lots of questions, pin down exactly what you expect and be willing to do your own quality control or hire people in country to do it for you before products ship! Clearly the OEM's in this case have had the circuit boards sanitized to keep the customer in the dark. It is the same juvenile behavior that used to be done to sand off the part numbers of semiconductors to ensure customer could not repair or reverse engineer the product. That sort of stuff never stops a competitor it only stops your customers from being well informed.
