#186389 - harder to mount Responding to: ???'s previous message |

easier/cheaper to manufacture but harder to mount (especially manually) I've heard stories that they can be quite tricky to mount automatically, too! Especially the really tiny ones (some of the SiLabs tiny QFNs are just a couple of mm square) - the trouble is, they just float off on the solder...! |

| QFN indicates PLCC, doesn't it? | 01/01/70 00:00 | |
| QFN is "lead-less" | 01/01/70 00:00 | |

| Cyanoacrylic type glue | 01/01/70 00:00 | |
| Is it used in mass production? | 01/01/70 00:00 | |
| I was wrong about the glue type for manufacture | 01/01/70 00:00 | |
| Nevertheless... | 01/01/70 00:00 | |

| I hope this becomes standardized ... | 01/01/70 00:00 | |
| Eh?? | 01/01/70 00:00 | |
| It seems that the industry's heading for a consensus | 01/01/70 00:00 | |
| PLCCs marked QFN | 01/01/70 00:00 | |
| Anyway, | 01/01/70 00:00 | |
| It doesn't have to be a PITA ... | 01/01/70 00:00 | |
| That's the point! | 01/01/70 00:00 | |
Yes, and your starting point matters a great deal | 01/01/70 00:00 |
