Member: 9700 Status: Offline Thanks Meter: 62 | @Bodzio: Interesting... but you never destroy pads with the grinder? I use other method, but not safe... with wnife and hot air... insert knife behind glue and ic... and pull up. (15% times broke pad) and after, remove glue with knife and 180º (like u) b.r. |

Member: 7062 Status: Offline Thanks Meter: 126 | hi. this way is not complete safe 100% cuz it migt reach the efficincy after destroy many pcb and this is my personal cooment 1- the drill is un easy to control 2- the powder from the ic while drilling is goes every where and cuz big mess 3- the components around the uem is very small and near 4- the tip of the drill you use is very expinsive and you can use one tip every 3 or 4 ic's . 5- the old fashion ay is more safe and its take time less than drilling way take . i m not attach hat wat but advise ppl with what i faced br., |

Member: 39601 Status: Offline Thanks Meter: 13 | Yes I add my voice to raheeeeb's , we test it allready ourselfs ( raheeeeb & myself ). That judjement doesnt come from nothing . Add one important thing , is that the diameter of the balls ( 0.3 mllm ) will not be equall in parallel connecting the IC to the PCB because of drimmelling variable depth from corner to corner . But noproblem it is a good tryall but we may take the risck sometimes |

Member: 2100 Status: Offline Thanks Meter: 40 | I also tried this solution a while ago, and some problems like raheeb and Medz point are true. Also the powder-dust is in my workshop in every corner, not to mention the health, maybee these IC's are in a "cancer" chemicals (or perhaps the glue?) For the "cornering" problem I was thinking to buy a support tool that hold the dremel firmly in place (with depth control) In a solderjig, it sould be possible to do the job more accurate |

Member: 10854 Status: Offline Sonork: 1578988 Thanks Meter: 3 | @gsmen That's the way... CNC drill is not so expensive, works much faster and there is no chance to damage board ( unless it's not firmly tighten in seat )... Plus, it has vacuum to suck in all dust... You can build one easily... Few stepping motors, pc interface and application to control coordinates... Or even you can buy LEGO kit and adapt it to hold modeling drill BR Vule |
