Hello Rob,

?

?Thanks for your e-mail i just found lurking in the wrong folder (my filters are complex and subject to the odd idiosyncrasy... ;))

It's an industrial device to clamp a signal from a pressure sensor at a given level to bypass safety features!

Its good to see the Kicad files contained everything required to complete the gerber file set.
So... what is it? ? A power supply?

Re: Are these sufficient files to have boards made in China please?

 

Hello Dave, and all who so kindly replied, apologies for my late
response, work took me away from home.

Special thanks to Dave who has been an absolute star in converting
these files to a supported format. I will now approach a couple of
fabrication houses and I'll report back as to how I get on, it's all
very much appreciated!!

Just for some information here......... for anyone who wants to get PCBs made in a fabrication house......

The bare minimum requirement to get a single sided copper PCB will be to

provide 4 files.

1. ONE copper bottom layer as a gerber file.

2. ONE solder mask file...also called RESIST file..... which defines where to have holes in the solder mask epoxy to expose cope to solder to.

Note that some fab houses will accept a drill file that tells where to put those solder mask holes

while other fab houses will only accept a gerber file for a maks file.

3. ONE EXCELLON format drill file which says where to poke holes in the PCB

4. ONE boarder outline gerber file that says how to slice the PCB to the correct size.

?

ALL OTHER files can be omitted.

They don't care if you have a silk screen to print on the top or the bottom.


Here is a perfect example of that minimalist file set...zipped and send to OSHPARK

that they created these two images then delivered the PCBs







so.....
all I am saying here is that if you have to reverse engineer a schematic and
you get as far as a schematic......
you really don't need the silk screen artwork to get more PCBs made.


Have fun.
I did.

Top silkscreen
Bottom Silkscreen if you have silkscreen on the bottom

Go to the PC board fab site, and then see what their requirements are, which files they want, and so on.

Take the files you have, hopefully produced by a CAM program, and zip them.? submit those files as if you were going to make a board.? If you can see everything you're supposed to see, then you've got the files.? There's also gerber viewer programs available.

If you don't have the files produced by the CAM program, then take the original kicad files, and run them through Kicad's CAM program.? Most pcboard houses that accept gerbers generally have a script you can use to make boards to their satisfaction.? SeeedStudio, for instance, accepts gerbers, and has downloadable programs for EAGLE (which I use) and Kicad, which I have yet to use.

Re: OT: Anodizing aluminium ...

 

开云体育

the sodium hydroxide is both a surface cleaner and acts as an electrolytic cavitator in the process.
It's etching lightly the surface & initiating a network of pores within the terminal (hardened) layer of the aluminum which will accept the pigments uniformly.
A critical detail, is only some aluminums are receptive of anodizing.
My preferences are 6061, 6063 & 5052 grades.

It’ll strip the oxide layer off as well, and giving the part a slight etch probably isn’t a bad idea.? It’ll eat the part completely if left in too long – try it with a drink can.? You wind up with the plastic layer.

Re: Microscopes for SMD soldering etc

 

开云体育

Hi Tron,

? Well, I ordered the kit from Whizoo so I may be asking some questions later when it's time to run it. Mainly profile info if you have any on various solder. If you just use the datasheet I can find that info, but any tweaks or tips and tricks will be useful. No rush as I will be figuring out the SMD circuit board layout at first and may even have to design a macro for a micro USB port.

Thanks,

Dave

@Dave,

I too went through the process of attempting to resolve the problem of soldering SMD components. I tried a variety of USB Microscopes because they were inexpensive while the vendors were promising performance that simply wasn't good enough. However, microscope also have their foibles. I came to find that its best to call the microscope company and tell'm your budget and your goal. If they are an authentic company, they'll help you make the correct choice.

If you are just soldering a few 1206 and 806s here and there, well its fairly easy to solder these by hand using a temperature controlled pencile soldering iron. If however, you are doing a bunch of boards with many different sized SMDs, I recommend ya take the extra effort to fabricate an SMD oven. The ovens are simple to make and are VERY easy and effective.

I used a Black & Decker 1200 Watt InfraWave toaster oven which have low mass 'crystal' heater elements that exhibit low thermal inertia.

Check out this inexpensive SMD oven controller and homebrew website.

I'm told that sodium bisulfate behaves like sulphuric acid when in solution under electrolysis.

I have no experience at all in this, I am NO chemist (well just what I remember from "O Level" chemistry way back in 1964 !!).

Steven,
? That's good info. Never looked into it much but that makes it a bit easier. Besides, I already have the sodium hydroxide as we used to make soap as a hobby/business years ago.

A knee jerk reaction to some acid attacks. You need a license to purchase over 15% concentration unless it is in a battery. You can get up to 2 years in jail for possessing or selling the stuff without a license.
To get a license you have to pay (of course), get a doctor's report and have a clean record with the police.? If you have had any mental illness or depression in the last 10 years forget about getting a license.
