#108524 - Bad Design? Responding to: ???'s previous message |
Erik Malund said:
That is bad design, a design should never consider ease of replacement, but always consider avoidance of replacement. If I ever considered ease of replacement of a part, I would immediately kick myself in the butt and redesign the circuit so no such concern would come up. I even apply the above to fuses, and have started using polyfuses. Erik You obviously never had to work on something someone else designed. That, in my opinion is the type of engineering arrogance that leads to things like pulling an entire engine/tranny to replace a steering rack. All engineers should consider ease of replacement, otherwise it's not a good design. Failures happen whether it's bad design or assembly problems or just bad components. Fired up now? Jon |

| more on relay ratings | 01/01/70 00:00 | |
| Yes of course | 01/01/70 00:00 | |

| ULN2003's doesn't easily burn | 01/01/70 00:00 | |
| Uce saturation voltage is rather high | 01/01/70 00:00 | |
| there is an alternative, search for it | 01/01/70 00:00 | |
| I agree | 01/01/70 00:00 | |
| That is bad design | 01/01/70 00:00 | |
| ULNs resist more... | 01/01/70 00:00 | |
| I would never suggest 74HC buffers for d | 01/01/70 00:00 | |
| Yes , you didn't | 01/01/70 00:00 | |
| I would like to see where that is, pleas | 01/01/70 00:00 | |
