If you want to examine SMT, then have a look at the Hammerhead here ->

Sprint Layout 5.0 is also good for SMT, i do have some smt libs in it.
But i never tried.
Will do!Comment

I made HH twice. First one, few years ago, didn't worked properly, but i am sure it was my fault. And second one recently (last year i think) working excellent! Both on same version of pcb, TH. Haven't tried SMT so far. Hopefully will try in future..Originally posted by Qiaozhi View Post

IGSL PCB's
Glad to hear the boards arrived ok
Hoping to have a play with the "Green" one this weekend, I have an original coil waiting !
It may well be the next board to be offered
I'd also love to have a go at SMD, and a project crying out for it is a pinpointer
A simple is essential, you don't want external controls on a pinpointer really, just a switch , a 15mm-18mm wide board would slip into a 19mm/22mm pipe nicely
Surf Pi works great with a ferrite rod coil but I fear has too many components for our first try and power may be an issue - a low power scheme is required for a pinpointer so small 6v/12v single cells can be used (like petrapin design) or 4 x AA max
If anyone knows of a scheme that is suitable or can adapt one I'll provide the boards

I made green one and it is working by the book. Only, proper coil i don't have right now. Had one recently and sold it!Originally posted by silverdog View PostGlad to hear the boards arrived ok

Didn't expected at the time that will need it soon!
IGSL, other hand, is not so comfortable to be turned to pp.
But recently i played with Aztec! Splendid for pp.
Already made it..but my pcb is so huge and ugly - i am ashamed to post it here on forums!

Aztec
Non-motion - ideal !
Strip out the Disc, batt check etc..
But what about power requirements ?Comment

Using a Schematic & PCB CAD Program for IGSL
What we need, because it significantly reduces the workload AND it allows changes and updates to be quickly and correctly made, is a professional schematic and PCB CAD package that is fully integrated. It could be two different packages that work fully together. I personally favor Eagle, because I have it, I am not set on it completely as long as I don't have to give any more money out!!Originally posted by ivconic View Post
KICAD and ExpressSCH & ExpressPCB are two further possibles that are all free, there are probably more that are free also.....
I almost forgot, there is a Free version of Eagle, with limitations that need not affect us in the slightest, as especially if we go to SMD compnents, the max PCB size that we need will really go down, even a carefully designed standard IGSL could be fitted on that size board they allow with a few tiny mods.....(the current IGSL PCB is 10 x 11 cm I believe)!
The limitations of Eagle free are:-
Limitations
The following limitations apply to the EAGLE Light Edition in general:
- The useable board area is limited to 100 x 80 mm (4 x 3.2 inches).
- Only two signal layers can be used (Top and Bottom).
- The schematic editor can only create one sheet.
Apart from these three limitations the EAGLE Light Edition can do anything the Professional Edition can do. You can even load, view and print drawings that exceed these limits!
The good part is that for anyone who really gets to like Eagle (not difficult!), they can eventually purchase a license and key it in and continue using it without a re-install.......
One schematic but it can be used either for SMD or normal components with minor changes......and will produce two radically different PCBs.....but at the same version level!!!
Once you have used it a few times there is little better around. Its basically still the program I used over 20 years ago (Vers.2.0), but with many important improvements.....I am now at 5.4, which is not the latest one, but more than good enough for my needs.....
Sprintlayout is not a good package for really professional use (we are professionals!!) , though many (here too) like laying out their own one-off PCBs with it, and for that its good, but as far as I am aware, there is no schematic program that can be used with it.....that is why it should be avoided completely. Even Abacom's own schematic program is not compatible!!! Now that is crazy!!!
Properly made updates to schematic and PCB are therefore a pain (but many do it without thinking) , as we have seen, Ivconic changes the PCB well before he changes the schematic, as I also would if I was using it.....it's two separate almost unrelated jobs.....bad news.
We should agree to a package between us, preferably free, that each can use when and how he himself wishes......
I vote for Eagle Free, especially if our aim is to go SMD/T.....the limitations will not affect us at all......

Cyanoacrylate (Super Glue) hardens in about 1 second flat if you sprinkle it with Baking Soda. It works as catalyst and make a cement.
It hardens so fast it gets hot. Try it.Comment

Eagle Free sounds great, but I like to make bigger boards for experimenting so I can get my hands in there and do hand-wiring if necessary on standard .1 inch hole perfboard and have room for mods, etc.Originally posted by der_fisherman View PostWhat we need, because it significantly reduces the workload AND it allows changes and updates to be quickly and correctly made, is a professional schematic and PCB CAD package that is fully integrated.

So I use ExpressPCB and ExpressSCH. They are not too bad, but one feature is missing that I would like... maybe if we all complain they would add it.
Feature: I would like to be able to import an image file into ExpressPCB to use as the background, and make it scalable.
That way you could easily re-draw any PCB layout you have an image of.
I've suggested it, but the bums haven't budged. They probably fear either copyright liability, or loss of business when people make their own PCBs. I think the web business model has shown giving away good free things helps expand your business... just wish they'd "get the picture"...

I agree with fisherman 100% on this one. Another possibility is Designspark PCB with Schematic design.Originally posted by der_fisherman View PostWhat we need, because it significantly reduces the workload AND it allows changes and updates to be quickly and correctly made, is a professional schematic and PCB CAD package that is fully integrated.

To all over you who are talking about Schematics and PCB design, firstly many thanks for your input, that is exactly what we need.
Simon had a good idea that sadly Express appear to only ignore, as its an excellent idea.
What about if we make a list of what we want in a package? Then compare each package and see which one fits our needs best of all......sadly Eagle cannot import a picture, but that is about the only real limitation, otherwise it does just about anything you could possibly need - and a lot more!!
