I don't doubt that but the decision to circumvent the regulations is made by
the customer, not the contract manufacturer. At least that's how my company
operates.73,Gary K9GS

WT1501CW - EMI I've seen and witnessed it many.....many times with SMPSs from
China overthe last 15 years or so. It happens more than you might imagine.
One yearof testing as a consultant, I had to send 100% of the SMPS's back for
lackof decoupling in either the AC or DC lines. The real estate was there
forthe components, but they were jumpered once the supply had passedregulatory
qualifications. Very common practice!!!Dave - WØLEVOn Thu, Nov 8, 2018 at
