MEP EP#222: Turning It On - New Design Checklists with James Lewis
James Lewis
His passion for teaching non-engineers has led him to create the Baldengineer Blog and the AddOhms video tutorial seriesWith 20 years of experience in electronics, marketing, sales, and teaching, James boils seemingly difficult concepts down to the core, so that anyone can learn what they need to finish that next great projectJames was on the previous MEP EP#141: It Depends – An In Depth Look at MLCCs with James LewisHow to test and validate if your new PCB Assembly is working properly
What do you do before power on?Component checks?Current limiting?Voltage limiting?The Smoke TestWhat do you do if it all goes up in smoke?Validating power systems or suppliesEquipment for testingIR cameras for looking for hot spotsMinimal viable electronic lab equipmentDigital Multimeterauto rangingtrue RMSmeasure/verify caps (but gotta take it out of circuit)Consider bench stylePower SupplyPower output, watch the power ratingsCurrent limiting (critical)Output controlAvoid the cheap ATX routeOscilloscope bandwidth vs sample ratechannel countbuilt-in AWGserial decodesProbesFunction GeneratorGreat for filters and to replace a clock, but how useful are they?All-In One devicesAnalog Discovery 2Great for turning-on boards from homeCompromised specs, but could be "good enough."Soldering StationThink about reworkCan you remove SMT?Hot air, etc.Will you need to add debug headers?
