Thank you Carol and Rob for the execllent 5 day lecture.

Iron

I use Advanced Circuits for fabrication and placement from Advanced Assembly for quick prototyping.  It is worth the cost for the time.  They can order parts as well (most from DigiKey).

Iron

VHDL, DSPs, very good and practical training. Thanks

Iron

hi, I manufacture pcb protypes on my own using serigraphy, I also order high volume from different PCB fabs in Mexico and Asia.

Iron

Good overview and pointers for a first board prototyping class. Rapid prototyping can be a critical capability

good walkthrough on fab and design package as a wrap-up

 

Nice Work!

What will MIT come up with next -- LEGO Mindstorms ??   :)

Would like to have seen the back-annotated schematic and updated BOM *(Bill of Materials, not Book of Mormon)...

LED + and LED - holes don't look aligned???

glad you archived these sessions!

I've ordered a few 2-layer PCBs for hobby purposes.  The first was made with KiCad and the others with DesignSpark.  But I learned a few things from Carol's lecture.

I use a batching service now called OSH Park (formerly Dorkbot PCB) with excellent output (boards are US made).  For my hobby use it's worth waiting a couple of weeks to save a couple hundred dollars compared to the cost of quick-turn places like Advanced Circuits.

Iron

Practical RF design, Signal Integrity and Power Integrity are the point of interest

Experienced with PCB design, fabrication and debugging

Howdy archived people!

 

Iron

I'd like to see the way these boards are dealt with on the factory floor

showing parts placement, threw hole soldering automated test inspection etc

But plan on doing it in the future

I havent ordered any pcbs for prototying

Hi picking the last day

 

no experience ordering pcbs

 

Iron

test 3

things have incremented on way to go.

Iron

thank you for the information

Iron

one more archive done.

 

Iron

better late than never!

Iron

Thanks Carol; excellent presentation

Iron

We should have another week with another proto project. It's very interesting

Iron

i'm ok with the course presented

Iron

Thanks for the information that you have provided this week.

Next time, I hope.

Iron

For a one stop proto shop try screamingcircuits.com

Iron

I had fun this week teaching. You guys are a great audience! Good luck to everyone.

Blogger

Thanks everyone for attending this week. And thanks Carol for your great programs.

Blogger

@Mr. E, Don't have any names for you. It would depend on the volume. If your are willing to wait and have enough volume, ask for their bottom price. Some manufacturer's here will have a relationship with a Chinese mfr and can handle it for you.

Blogger

Thank you for a good series, looking forward to more, next time.

Iron

@Mr. E, If you mean the little board in the green square, that's just an icon.

Blogger

@Carol: Just out of curiosity: would you name some fab houses that populate the PCB as well as make it? Sort of a "one stop shop"?

Iron

@Carol: I just figured there were some special features on the board on slide 6 that I was overlooking.

Iron

Rob: Already playong back #4. :-) Will be covering tutorial and re-doing entire series. It helps to try the work a few days later -- to see if you still remeber the lessons.

Currently working on a board I wish to prototype -- no tools not enough knowledge. Now I can try at least!

Iron

@caa028, Thanks. You've made my Friday!

Blogger

@Dave, I agree, Carol's presentation included great detail. Plus, they can be played back if you need to review the info.

Blogger

Agree with dave - this weeks lectures are probably the most useful out of the whole series...

Iron

Gotta get back to the grindstone  Bye   Bye until your next lecture

@Dave, That's awesome! Thank you.

Blogger

Your welcome and best wishes for a great future.

For my purposes this week goes to Top Five list. Thanks!

Iron

@Chris, Thanks so much! I really appreciate that. 

Blogger

Work is calling, great lecture hope to see more in the future with other neet stuff such as impedance matching etc

Iron

@Mr. E, I was playing around and the screen capture doesn't match the quotes on the left. The quotes are correct. Good eye, I'm glad someone's paying close attention.

Blogger

I  listened all week to the lectures.  You really did a great job.  Better yet would be to order boards and stuff them and then test circuit.   But that would cost big $$$.

I have File>>>>Edit>>>>View>>>>Add>>>Sitting>>>Tools>>>>Window>>>Help. That is it.

good info - thank you

Iron

I'll ask them at Sunstone, they have excellent tech support  ... thanks

Carol mentioned extra charge for less than 10 mil pitch. Sometimes there is a reason.

To avoid Tin Whiskers use 6 mil size for pitch. A 6 mil pitch allows a  ROHS exemption application so you can use standard solder and avoid "Tin Whisker" problem.

Iron

@Don, DesignSpark does have autorouting and it is free.

Blogger

Today's program is now available for archived viewing -- as with all of this week's programs with Carol Lenk.

Blogger

@Carol: What caused the sample PCB on slide 6 to have a total cost of $404.07 rather than the standard price of $273?

Iron

@mRlu2012, don't know off the top of my head. Try searching their website. Maybe a full panel (12x24")?

Blogger

PCB123 does not have the POUR copper function ... Oh well ...

@Chris, try pouring a copper area. I talked about that yesterday.

Blogger

What is the limit in PCB size for this standar service?

IRON
Blogger

@gordonnex, that's up to Rob and DesignNews.  It's fine with me. Or get me your email.

Blogger

Thank you Carol, Rob, Design News, Digikey and my brain for making this great week possible.

Iron

@everyone, I'd like comments by people that have used both DesignSpark and Eagle free version. What did you like most in each?

Iron

Adding ground planes on two layer boards with DIP packages.

@ROB & @Carol-  Thanks for an informative week.

Iron

Many thanks to you both for your work on this series.  Enjoy the weekend!

Iron

@Kinda, did you add a folder first? In Library Manager, the rightmost tab...

 

Blogger

Why do the prices go UP with quantity?

IRON
Blogger

Question: Are PCB Artist and DesignSpark files interchangeable?  I thought Carol mentioned they shared the sam internals

IRON
Blogger

I was not able to add item to the library.

Thanks Carol and Rob for the interesting week. Pointing me to DesignSpark was quite useful for learning PCB design on a tight budget. Happy Friday and see all next time.

Iron

I am interested in more L.E.D.s for residential / commercial & industrial uses.

Iron

You're welcome to all.

Blogger

Can we get a copy of the designspark & gerber files?

IRON
Blogger

@Rob- Good intro content, how about autorouting?

Iron

PCBArtist does not allow any imports or exports. You can only get gerbers after an order. And you cannot take gerbers and translate back to layout software.

Blogger

Great series. Thank you.

Iron

Express PCB is much simpler to use for small and proto projects. You have to use their board service but their quality and service are excellent.

 

Iron

Great class. Thanks Carol!

Iron

Does any free prototype layout software have autorouting?

 

Don_Neal

Iron

If we are talking about PCBs, how about EMC & ESD design issues in PCB?

Iron

Thank you Carol. I look forward to your next series.

Gold

Thank you Carol, and Rob. Helpful info here.

Iron

Thanks Carol and Rob.

Iron

Where is chat link?

 

Iron

design tips were great, would like more

thanks

 

I would like to know more about RF PCB layout and  Annetena Impedance matching on PCB

Running traces on to a ground plane

 

@mRlu2012 - usually 12" x 12" for proto runs.

Iron

Great week, thank you!   :)

We're now on slide 12.

Blogger

What is the limit in PCB size for this standar service?

Iron

@1ifrpilot -- it does that to me every time I download.  Just do it again and choose Overwrite Yes.  It always works the 2nd time.  ??? It just does.

Iron

We're now on slide 11.

Blogger

Check out AP Circuits for very limited, low cost protos:

 http://www.apcircuits.com/ap/calculator

Iron

I've used myropcb, in canada.

Iron

We've been happy with Accutrace's service for prototyping.  2 layer boards $10 ea, min qty 10 - top silkscreen only, or 4 layer boards $30 ea. 1 week turnaround.

Iron

@Rob - i think, either seed or itead will be enough for my prototypes...

Iron

When I tried to download the slide deck, it said the .PPS file was corrupt.  Can you check this?

 

Iron

We're now on slide 10.

Blogger

Just so you know, I'll copy any questions you have and post them at the top when Carol comes on to chat after her talk.

Blogger

@Rob - sure, will give it a try... but not at the PCB artist prices...

Iron

We're now on slide nine.

Blogger

Price per board does not go up. The price is for the total order.

 

Gold

initial prototypes live on a breadboard before the perfboard unit.

Iron

We're now on slide eight.

Blogger

@BanjomanF It is total cost, not cost/board,

Iron

Why do the prices go UP with quantity?

Silver

We're now on slide seven.

Blogger

would like to do more prototyping PCB for personal projects. most are on perf board with #30 wire soldered point-to-point to make sure the circuit works as expected.

Iron

This is a great idea for prototyping. No more breadboard...

Iron

Got a prototype requirement coming up soon.

Iron

Will be doing several prototypes now that I have software.

Iron

We're now on slide six.

Blogger

How many of you are looking to do more in prototyping?

Blogger

To double check package layouts it helps to print the top layer on a good laser printer, as well as the bottom layer, mirrored. Then actually put your components on the paper to make sure everything is OK.

 

Iron

Question: Are PCB Artist and DesignSpark files interchangeable?  I thought Carol mentioned they shared the sam internals

Iron

We're now on slide five.

Blogger

(1) Make sure that your holes are big enough.  For plated through holes, allow for the plating.

(2) Depending on your requirements, you may want some holes are to be plated, and others you want to be clear.  Don't forget to check.   It is painful when you short a top layer to the bottom layer.

Iron

Can we get a copy of the designspark & gerber files?

Iron

We're now on slide four.

Blogger

Make sure you know what color represents the top component layer and what color represents the bottom component layer. Especially important when working with different layout packages !

Iron

what layer is the board outline on?

lessons learned... check the component footprint, check the footprint, check the footprint for the package being used. then make sure it's not inverted!

Iron

Always try to maximize the usage of the panel.

Iron

What are the lessons learned on ordering PCBs?

Blogger

We're now on slide three.

Blogger

I ordered many PCB prototypes from different manufacturers like Beta-Layout, Contag, Straschu, Würth, Pridana, ...

Iron

It really helps to talk with the vendor--it can save you lots of money.  Also, many vendors have standard design rules.  If you meet these rules your board will cost less.  For example, one 8 mil trace can add 10 or 20% to the board cost if the vendor's standard is 10 mil traces.

Iron

@Rob Generally good, never the quality I usually expect and little room for modification once they are in the flow. There are two streams: one for prototyping and another for production quantities. Some houses want it panelized complete with registrations, others will want to do that themselves.

Iron

Real easy ordering with PCB123 'Sunstone  ... Just download file and hyour done.

Ordered PCB's many times.

Have ordered many prototype boards both for experimental and pre-production runs, from various sources over the years.

Iron

@Rob: have not personally ordered a PCB before.

Iron

Not ordered PCBs for many years. Will soon though.

Iron

None. I Mill my own board.

Iron

I've ordered from pcbcart.com

Iron

no direct experience in ordering PCB for prototypes. aware of the process though.

Iron

Good afternoon, Carol.

 

Iron

@Rob - have not ordered any yet...

Iron

Never ordered PCB before,  working on design now.

Iron

We're now on slide two.
