\n151 FUNcube Dongles after HPF Rework, ready for placing in enclosures.<\/em><\/p>\n
\nFirmware programming and system test. I received 151 units on lunchtime on Friday. By Saturday lunchtime all 151 had been tested and 16 units with faults had been fixed.<\/p>\n
\nThe HPF rework and retest. I discovered that the LNA performance degradation and 1nF capacitor cracks are definitely caused by temperature fatigue. After the first ten units (four LNAs failed or degraded!), I dropped the tweezer temperature to 305 deg C (was 350 deg C) and the iron temp to 260 deg C (was 320 deg C) led to only one LNA replacement and no cap failures, previously I’d have had to change dozens of LNAs after rework. Only two units required other HPF fixes due to iron operator error.<\/p>\n
\nEnclosure labeling.<\/p>\n
\nPopulating enclosures and retest. 100% success and no rework required!<\/p>\n
\nLabeling envelopes.<\/p>\n
