BOM Check, recommendation, design modification
By the end of the design stage, the R&D engineer will ask the purchasing team or the EMS contractor to quote the BOM for prototype manufacturing purpose. Here will start with headaches! First search for real components based on very rough descriptions, take advantage of the few MPNs provided and finally detect that some components are obsolete, or no inventory available or requires large MOQ!
Some component modifications may be mandatory, requiring design modification, project schedule will be delayed.
