Hi Don I am going to try making stencils with a laser engraver that will last long enough for a few prototypes. The idea is, to treat it as a printer/plotter...
Interesting idea Tom. I've never used one of them before, but the theory seems sound. A few things come to mind. How your material deals with the heat...
Hi Don There an email last night, said the laser shipped, have not checked to see when it will arrive. It is a 60 watt system I bought on eBay, I will know...
Hi Don The laser is supposed to get here this morning, should have it up by next week. Ultem at 0.010" thick isn't as expensive as I thought, and it may be a...
I'm hoping that your 60 watt laser can be turned down. That might be overkill. While you're working on the laser engraver method, who wants to work on...
Hi Don One problem with direct application of solder paste is viscosity and a second one is particle size. Viscosity might be addressed with a different...
Hi Don ... My preference is for Promosol, when I can get it. Their vehicle and flux are very good. Tom ... The fish are biting. Get more visitors on your...
Hi Don The laser ran today, cut some plastic with it. There will be some fiddling around to get Express PCB files into a print file format that will work...
That's great to hear. What file format/software is normally used with the engraver? I assume that you can't simply print to the device by pciking it from the...
Hi Don It will work with DXF for sure, that's what I used Saturday. It is also supposed to work with PLT, BMP, and a couple of others that I can't remember (...
I have used a similar method. BUT, instead of printing in color I just choose top/bottom layer and NOT select color. Using Adobe PDF as my printer. What I get...
... the symbol as it does with the Library Symbols? If the problem is that the text won't behave, the fix is easy. If you are starting with a standard symbol...
I have a circuit i have been working on for about two weeks now with no luck. I made the schematic and then done the pcb layout and ordered the boards. On...
The file is in the files section. (PCB.ZIP) ... with no ... ordered the ... jumped with ... to J1. ... not ... the ... points ... uploaded ... QUFWKEqFYKZ\ ......
... Just a quick perusal. On the PCB, pad (pin9 of SC1)and trace at x=0.650/y=0.650 on bottom are not connected to anything. I don't see them on the SCH, so...
A while ago I had some boards made though ExpressPCB's "MiniBoard" service, and they were the lead-free type as that was the only option available after their...
Considering the small size of an MLF package, I'd like to know if anyone has successfully made boards using one. I've created the package according to the...
... You can view the solder mask layer if you wish. Select "Options..." from the View menu and you'll see a checkbox for the top and bottom solder mask...
... That's what I was thinking. I have a few samples on the way just for that purpose. I did view the solder mask layer. Seems to me that it will require ...
Sorry if this is an old topic; I didn't happen to see anything like this in the old posts. I'm trying to build a component that has .4 x 2 mm pads spaced .65...
Don't know the answer, Bob. But, I have found the same anomaly. I directly enter the x/y position for a component or pad and later found it may have shifted...
... Or maybe it stores all coordinates internally in inches (or binary) and does so without enough significant digits to prevent a tiny shift when converting...
I am looking for *.s and *.p files for the 16-Pin standard LCD. The display I am interested in is a generic 2x16 with backlighting. Any help? Thanks!...
Could you post a part numeber of your LCD display or a link to the datasheet? I just never heard about a standard form factor for the LCD modules, and I'm...
Anyone aware of any progress on efforts by ExpressPCB to provide a solder paste stencil service. Seems I recall they were working toward providing that...
Hello Ed I am working on a method for this using the DXF file from Express PCB output and an engraving laser, in ten-mil thick polymer. Fixturing is the next...
