How do other folks handle
vias on double sided pcbs?
I have tried two methods
1. WIRE
Place a hole close to each via
and use this to solder in a piece of
wire. I put a letter "v" in copper
on the bottom side of board next
to the hole so I can quickly check
that all the vias are taken care of.
Of course this means you have to
drill more pcb holes.
2. INSERTS
I got some gold plated MillMax
inserts that fit into a drill hole and
are hollow and big enough for typical
resistor and dip leads. I think the
OD is about 0.039". You have to
be careful when you solder them in
because the solder tends to wick
into the hole. I do not have the
part number now and the last time
I looked no one (Digikey has
some MillMax) was carrying them.
This seems to be the neatist
solution to the hombrew via
problem. However I only have
a few left, so I will have to find
another source. If I have to buy
thousands, is anyone interested in
a group buy?
Comments?

Other uses for Blue Sheets
I was messing around with all these old blue sheets.
Then I thought about others that wanted to silk-screen the component side of
the board. So I took the old Blue sheet and ironed on the finished component
side.
Sure enough it sticks better on the bare PCB than on copper and has a nice
blue lettering. I used scotch bright on it and it doesn't come off just
lightened up.
It didn't stick where there were holes, so you need to put it on before you
drill.
I'd have to say blue sheets work great as a cheap silk screen.

Re: New file uploaded to Homebrew_PCBs
I didn't find Eagle that user friendly but that was a few version back. I
will give it a shot again but the French program and the PcLogic, which I
purchased, are simple to use and generate very good boards. Both have Gerber
274x for sending in if you want someone else to make your board.
One of the nice features of PcLogic is you can throw some pads down in the
middle of your drawing.Then you can draw the outline of the part and with a
few clicks make that a part and name it. For $25 you can't beat it for the
lite version if you don't need autorouter.
The French program is for people getting started and need something simple
and free. Everyone knows where the File is at the top, all windows programs
are the same in general and numbers are numbers a Lm339 is a Lm339 in
French.

HP7550a plotter and Windows 2K
Does anyone have any experience connecting an HP7550A plotter to Windows
2000?
I am having some problems with cables and drivers.
I plan on using this plotter to directly plot onto a PCB for etching if I
can get it to work.
Thanks

What to do if you have a virus
First off, let's take this off list. 2nd, get a virus checker. You should be running one. My wife wasn't, her computer got infected without even getting it by email, we think it was from someone's website. 3 days after she started running without a virus checker, Norton Antivirus reported more than 2000 infected files, none could be cleaned but only quarantined. I ended up doing an FDisk, Format, and Reinstall. 3rd, -don't- -open- -executable- -attachments-! Not without scanning with a current virus checker first, and even then if you weren't expecting it, don't open it. So many people tell me, "But I only open them if they are from someone I know!" Well, duh, that is how the virus propogates. It uses your list of email addresses so you are SENDING IT TO PEOPLE YOU KNOW!! 4th, change your default settings in Windblows- set it so you can see the three letter extension for -all- filetypes. IE, turn off "hide extension for registered file types". Note the name of the virus below- If Windblows hides the ".scr" (script), then it looks like an MP3. About the only things that can't hide viruses these days are JPG, GIF, PNG, RTF, and TXT files. Please, last word on the list on viruses. Try the newsgroup alt.comp.anti-virus and you'll get a lot more experienced people. I use Norton AntiVirus from Symantec. You can download a 30 day trial version.
