Expensive test gear?
Most useful is a magnifying glass to look for dry joints I'd estimate that 90% of rigs given to me to repair are resolved by optical examination followed by solder re-flowing. Soldering irons - to the bottom of one of your smaller bits, attach a chocolate box connector (& remove the plastic covering before it melts and fills the shack with toxic fumes!) To the other half of the chocolate box connector, attach a range of obscure "bits" of metal that you've fashioned to deal with the various SMD shapes. Most Useful is an old Henley "Solon" bit that has a slot filed in it to sit either side of an SMD R or C. "SMD rework station"??? Fashion from bits left over from your Mecaano set - create an overarm with a spring loaded plunger to bear down onto the component to prevent tombstoning. Working end of plunger to be wooden, cocktail stick or chopstick serves nicely. Sacrificial 'cos slowly burns away. Only once had a problem with resins oozing out from wood. Come on, chaps, this is simple mechanical bodging, a trivial matter for any self-respecting _REAL_ Radio Ham! (Unless you fail to secure your PCB before rework, it ain't "Rock It" Science :-) ) "Only used for the one repair"??? Is that a CBer talking? Surely the essence of _REAL_ Ham Radio is that you're using this type of equipment all the time? (Not true for a CBer-masquerading- as-a-Radio-Ham, though!) "today's microprocessor, DSP and firmware laiden transceivers"? All _REAL_ Radio Hams thrive on how thing work and how to modify them! Indeed, if you're a _REAL_ Radio Ham, then your transceiver will have been designed, constructed and modified by you, so the " microprocessor, DSP and firmware" will be your design anyway and therefore not a problem. "laiden"????? ITYM "laden". I'd advise you not to seek a job in education because of that! "Leigh" wrote in message ... G.A.Evans G4SDW wrote: Ham Radio is a technical pursuit for gentleman. Those who think that they are Radio Hams but send their rigs back for repair are "CBers-masquerading-as-Radio-Hams", no more, no less. But with today's microprocessor, DSP and firmware laiden transceivers, would repair be both possible and cost-effective once the radio amateur has purchased a SMD rework station and expensive test gear, etc, that would only be used for the one repair, etc? |
