Here, there is one I used to follow. 1. Prepare standard assembly drawing. 2. Select the components you want to higlight. If the only common properties of those components that are to be selected are Footprint (like 0805) and Comment (like 10k) then you may do it using Global Edit, or Query Manager in PCB. If the selection criteria is more complicated then use Global Edit in Sch Editor and then use Tools-Select PCB Components. 3. Cut (Ctrl+X) selected components (note the reference point). 4. Modify remaining components to make them less visible, e.g.: - Hide their designators - Make their outlines very thin (e.g. 1mil) (First Un-Lock primitives of all components, then change globally the width of all tracks and arcs on Top Overlay to 1 mil, then Lock primitives back). 5. Paste back the components you previously removed at the same reference point. If you use colour printer then there are obviously more options.

[EMAIL PROTECTED] wrote: An easier method for doing this hand-soldering is to use what is known as a mini-wave tip. It's a concave cupped tip that you fill with solder, and use exactly as you describe - drag it along the pads. If the pads have been designed right, it's really easy to do. Even without any special allowances, it's fairly easy to do. I have no trouble with any TSSOP/TQFP/whatever that I've tried. Make sure you put a liberal layer of flux along the pads you are to solder, though. I also do 0402 components by hand sometimes, and regularly do 0603 components. All without visual aids, although we do have stereo microscopes available if required. SMT is not all that hard, and in fact I'd venture to suggest it's less of a PITA than through-hole technology. Especially for rework - it's much easier to remove 0603 components than it is to remove through-hole components. TQFP devices are another story, of course... I agree, The most difficult thing about reworking SMT is convincing yourself you can do it. I have regularly reworked a wide range of devices with no problems. I find that contact methods using solder wire and a soldering iron are much more reliable than methods using hot air and I now only use hot air where other methods can't be used or for 0402 devices. I have also found that a 2(ish) mm chisel tip works better for me than a miniwave tip when drag soldering. * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * To post a message: mailto:[EMAIL PROTECTED] * * To leave this list visit: * http://www.techservinc.com/protelusers/leave.html * * Contact the list manager: * mailto:[EMAIL PROTECTED] * * Forum Guidelines Rules: * http://www.techservinc.com/protelusers/forumrules.html * * Browse or Search previous postings: * http://www.mail-archive.com/[EMAIL PROTECTED] * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *

It's great for both putting parts on taking everything off in a single shot. Especially if you turn the air flow right up - it nicely cleans everything of the board in one go :-) We do a fair bit of hand assembly. We also use many of the techniques discussed. The hand assembly is pretty much only for prototyping though, not production release (volumes kill that). We are close by a contract assy shop and they have a service where we can duck down and get them to run just the fine line stuff through a re-work station. This is faster than us mucking about if there is more than one or two devices. It saves time looking for those occasional extremely fine shorts that can happen every so often. For repair and re-work we use a Hakko air gun - you have to be careful with it as it can easily burn components and the PCB.

Re: [PEDA] Prototype Assembly House
Ivan, When soldering fine pitch parts, we use lots of liquid flux and then simply drag a tinned iron across the pins. The best solder joints around and the flux eliminates bridging. Don't over do the solder on the iron tip. Takes a few tries to develop tricks, but I have never failed yet. Of course you then have to rinse off the flux. I use isopropyl and clean compressed air. Haven't figured out BGAs by hand yet, but it will have to happen soon. Paste and an hot air knife???

Re: [PEDA] Prototype Assembly House
Jon, There could be problems with hand soldered components. Ceramic capacitors, for example has a tendency to break and become resistor with 10-100 Ohm resistance. Probable, due to thermal tension from manual soldering. I had such problems in the past. Worst of all, it usually happens weeks or even month later. That's why I don't want hand-soldered SMT board go to the field. Reards, Yuriy.

(Heh, I have trained my wife, who finds sewing to be almost beyond her, to do modest SMT work.) I'm currently working with a number of chips with .5 mm lead pitch, and 0402 passives, and I do it all by hand. Now, BGAs, I admit, are beyond the tools and techniques I have developed. I think I could do a BGA, but I'd have absolutely no way to check it, other than boundary scan and similar electrical testing. So, that is one place that simple manual techniques really hit the wall.

I HAVE seen broken caps on rare occasions, and fixed them. But, I've never seen this sort of trouble, except in manual rework. I definitely do not reuse removed SMT components except on VERY prototype pieces. My feeling is that manual soldering subjects parts to MUCH less thermal stress than IR reflow systems. Since these ceramic parts have VASTLY lower TCE than the PC board, the idea that fully heating the entire PCB and components and letting them cool together doesn't seem to be of any benefit to me.

Re: [PEDA] Prototype Assembly House
An easier method for doing this hand-soldering is to use what is known as a mini-wave tip. It's a concave cupped tip that you fill with solder, and use exactly as you describe - drag it along the pads. If the pads have been designed right, it's really easy to do. Even without any special allowances, it's fairly easy to do. I have no trouble with any TSSOP/TQFP/whatever that I've tried. Make sure you put a liberal layer of flux along the pads you are to solder, though. I also do 0402 components by hand sometimes, and regularly do 0603 components. All without visual aids, although we do have stereo microscopes available if required. SMT is not all that hard, and in fact I'd venture to suggest it's less of a PITA than through-hole technology. Especially for rework - it's much easier to remove 0603 components than it is to remove through-hole components. TQFP devices are another story, of course...

Re: [PEDA] Prototype Assembly House
What we do here is to make a DIP-like prototype board for our FPGA's, complete with clock chip, configuration PROM, programming header, etc etc, with all the I/O's to pins on board. We can either use this for prototyping on bread board, or can even put it into a socket (made up of strip-header sockets) on a production board. Admittedly, we don't use very high speed on our devices (generally 10MHz clock, sometimes we go to 40), but it works well for us. We even do it for small micros - you can put all the support chips (crystal, decoupling caps, sometimes 3V3 voltage regulator, etc) on the one board, and just break out the I/Os and power. You can use it as a macro component, and also if a new generation of the micro/FPGA comes around, you aren't locked in on the major production boards, only the smaller, cheaper daughter boards. This methodology also gives leverage into new projects quickly - the macro components are already made up, so if you need one, you just plug it into a bread board, and you have an instant prototype.

Another advantage to DIPs is that you can use a socket for them. This is good for those times you want to make a particular feature (such as ADC) an extra cost option. If someone wants the option, you plug in the part. That way you don't have to make different builds. Yes, I know there exist sockets for fine pitch SMT parts. They are expensive - usually more than the part you want to put in the socket. Ever wonder why Microchip makes so many DIP package chips? ;-) I like technologies that are appropriate for the given application. Many times a DIP is better than SMT. Sometimes SMT is better.

Re: [PEDA] Prototype Assembly House
Removing TQFP/TSSOP etc is very easy to do. Use a brand new razor knife and carefully cut the leads where they enter the plastic body of the chip. About 5-10 gentle cuts per side is enough to cut through the leads and the chip falls out. Then use a low temp iron and remove the bits of leads remaining.

Hi Yuriy, We've had very good luck with quality and quick turn around with Advanced Circuits, www.4pcd.com. I haven't done much with price comparison, though. Good luck.

Tom, Unfortunately, I did not make it clear. I am interested in *assembly* service, not PCB itself. As for PCB, I second your opinion about www.4pcb.com. Use them a lot. Regards, Yuriy.

Re: [PEDA] Prototype Assembly House
I've had very good results with Argo Transdata Corp, Clinton CT. They are quite happy to assemble quantities of 5 or 10 boards. Quality is excellent, and turn around can be as short as a week or so. I supply the boards (advanced pcb) and all parts, bom, and an ascii pcb file (they don't want the pick and place). For more detail, call or write offline.
