frailn Posted December 11, 2008 Report Share Posted December 11, 2008 For you MIDIbox FM fans, I found a Deluxe SMD Learn to Solder Kit for $28.95 USD. Free shipping until December 17th (just type in free shipping in the order comments box). Would be good for practice before taking your hand to the MIDIbox build. Here's the skinny:Surface mount technology uses tiny leadless components, known as surface mount devices (SMDs), that are quickly replacing standard electronic components. Currently, most new electronic equipment incorporates this exciting new technology.By completing this course, the student learns concepts about surface mount technology (SMT) such as: " Different Types of Surface Mount Devices (SMDs) " Various Types of Surface Mount Assemblies " Automated Soldering Methods " The Stages of Manual and Automated Assembly Processes of Surface Mount Circuits The student gains experience identifying, soldering and using surface mount devices by physically building an actual working surface mount technology project.This course is the perfect introduction to SMT and does not require any previous knowledge of the topic. It was designed so that the teacher foes not need to be involved (unless he or she desires to be). The course is self-contained and reusable with the exception of the included "Learn to Solder Kit".A small soldering iron with a fine pint and some solder is all that is required to build the included kit.The Introduction to Surface Mount Technology Training Course with experimentation and project building comes with a detailed instruction manual, identification parts (both SMD and Standard), one "Deluxe SMD Learn to Solder Kit" and a magnifier with tweezers.

nILS Posted December 12, 2008 Report Share Posted December 12, 2008 Personally I like the "get a bunch of cheap chips, no matter what they actually do and some test pcbs (from mouser, reichelt or conrad) and just try" approach better.

That will teach me to properly read the item description. :-[ Quote Link to comment Share on other sites More sharing options...
TheAncientOne Posted December 16, 2008 Report Share Posted December 16, 2008 I'm in the same boat. Anybody want a bunch of TL072 and LM2904's in SMT - cheap - like 10p each?I had a first go by heat gunning some old chips off scrap computer boards, cleaning up the boards and then soldering them back on.Still found the AVRx board a major test of skill, though the chips on the GM5 and the x0xb0x were easier after that.If I can get a good result with my eyesight, then it's just a matter of practice.

And i ve soldered just 3 SMD chips! All 3 of them worked at first attempt. Quote Link to comment Share on other sites More sharing options...

Goblinz Posted December 18, 2008 Report Share Posted December 18, 2008 I also ordered some SMT IC's in error. SOme of the 512k bank stick IC's, they look very tricky to solder, the pads may even be underneath if I remember correctly! Quote Link to comment Share on other sites More sharing options...
TheAncientOne Posted December 18, 2008 Report Share Posted December 18, 2008 If the chips are expensive, and cost more than the adapters, then this is an answer.http://www.futurlec.com/SMD_Adapters.shtml Quote Link to comment Share on other sites More sharing options...
lucem Posted December 31, 2008 Report Share Posted December 31, 2008 TQFP100, soldered by hand, no problem.Gonna go for TQFP244 (FPGA and CPLD) soon and expect no problems, too.@TheProf:Those adapters are fine, really, but still people will have to solder the ICs to the adapters.

sakodak Posted January 30, 2009 Report Share Posted January 30, 2009 A small soldering iron with a fine pintThat is the best advice for smd: have a fine pint. Or three. Quote Link to comment Share on other sites More sharing options...
frailn Posted January 30, 2009 Author Report Share Posted January 30, 2009 If the chips are expensive, and cost more than the adapters, then this is an answer.So, are you thinking by using the adapters, if you mess up the SMD soldering, then you can just replace the adapter and start over rather than tearing up a good MidiBox PCB?

No actually, though that is a good point. I was actually thinking of times when the SMT version of a chip is you can easily buy, or is much cheaper than the DIL version.The AD633 multiplier used in Marc bareille's 'Warp' ring modulator is a good example. http://m.bareille.free.fr/modular1/warp633/warp633.htm.In my case I used them because I had cheap adaptors from China, and a lot of SMT good quality op-amps.
