Tooling up for SMT
I'm considering tooling up for surface mount devices and
How much is this going to cost? I'd be doing it is stages . Soldering de-soldering of discrete devices then for instance tool up test gear probes then chip probes and blocks. Anyone tooled up for surface mount care to go through the initial kit they got, capital outlays, how much it is used and if it has been profitable or not. What is considered essential kit to start with? -- Z Remove all Zeds in e-mail address to reply. |

Tooling up for SMT
And a few extra points
If you can't get the tugging wires under the IC then pass under a few pins at each corner. Because this tugging frees the IC at the earlies moment the solder on the board is not fully melted and leaves a profile for localising the new IC in place and then solder pin by pin |

Tooling up for SMT
Hakko makes a tool, the Mach-FP which is inexpensive for SMD removal. Some
practice is required to become proficient with this tool, however I've been using one for almost 7 years now and haven't damaged any PCB's. http://www.hakkousa.com/products.asp?PID=Mach-FP&page=1 Handpiece with the tips runs about $250 USD. SMD components can be reinstalled with a standard soldering iron easily with the appropriate technique. -- Jammy Harbin J & J Electronics, Inc. 227 S. 4th St. Selmer, TN 38375 731-645-3311 "N Cook" wrote in message ...

Tooling up for SMT
Hi!
I've used JBC products for PC mainboard repair, a lot cheaper than others. Used it for QFPs and PLCCs. It costs US$ 2,390 with all accessories for the JT7000 (http://www.howardelectronics.com/jbc/jt7000.html) . I've evaluated other brands, they don't come close with ease of use. A medium sized QFP can be removed in 20 secs! Quick removal translates to less PCB/chip damage. Removing the SMT part is the easy part, profitabilty is another. Regards. |

Tooling up for SMT
Thanks for the tips. S/M is not something I do much of so buying the the kit is a bit on the extravagant side just now. I had a look on your tips section of your website. The book tips about a third of the way down http://www.divdev.fsnet.co.uk/tips2.htm ; have the repairs held up over two to three years? -- Z Remove all Zeds in e-mail address to reply. If you mean the anti-acidic treatment. Yes seems to halt the rot, reduces the browning but perhaps black print is less black and the wet process does ruin any binding. As confirmation I still do it now and again to different books electronic hints and repair briefs , schematics/manuals list on http://homepages.tcp.co.uk/~diverse Nigel, Diverse Devices,Southampton, England |
