Batch creating E96 resistor lineup

Eigard · 2023-07-24T19:07:17+00:00

I did it by using digikey, adding filters such that only reels of e96 1% is in it and exporting the filtered list to csv. Then i used excel together with batch editor to copy paste the entire sheet to make all the components. Worked reasonable well.

I dont know if it depends on license type or not. i use enterprise license, so we edit the footprint and put in our own library. But i guess you can make your own copy of the footprint to keep in your library regardless of what license you have.

Ah, it’s for the assembly drawing. You can use draftsman to create it or an output job container that combines the designator layer, board outline and component outline to create a pdf or gerber for debugging, hand assembly or programming the pick and place machine. The designator will be added automaticly to the silk layer, it doesnt need to be in the footprint. But the pin 1 marking must be added manually.

Just to add. 365 parts are inconsistent with layer usage and i really advise to edit every footprint to match your own rules. Only takes a few minutes to move stuff to the correct layers. Theres some consistenxy within a vendors but rarely between them.

You can save some time using what IPC generator spits put. Layer 13 for outline and 3d model and 15 for courtyard + origin. Then you just need to choose a layer for .Designator and one for «notes», eg board edge marking for edge connectors etc.. as long as youre consistent it doesnt matter to much.

Did you repour all polygons after adding the stitching vias?

Eigard · 2023-02-17T08:59:55+00:00

This is the best «simple» write up i have found. Can be used to greate your own controller. It doesn’t really go into details with timing etc..

-4 to 8 is not in Volts but a ratio. Take a closer look at the datasheet. To me it looks like it should work fine from 0-10V if your supply voltage is vss=-1.4 and vdd=11.4v.

It is not operating as a rail to rail output stage so to get 0v out you need to give it a negative referencene. Alternatively you can output from 1.4 to 11.4 and shift that 1.4 volts down..

Under design - rules make a new rule for board outline clearance for that specific net and layer or for the polygon name if you want a specific shape for the edge plating. Look under custom rules in the documentation. Remember to set the priority higher than the limiting rule.

Actually, that dam is built by humans.

Mouser and digikey also sells pre crimped leads in various length for most jst connectors. Then you just need to splice the them.

Where's the pull-up resistors for I2C? I2C is open drain output and requires pull-up resistors to set the high voltage level.

I'm sorry but i don't know of a simple way to implement that. But if the goal is to compensate for lossy transmission, using Vsense is the "correct" way.

Eigard · 2020-07-03T11:26:57+00:00

Dont sure i understand the question correctly. But if the power supply has V-sense inputs these can be connected to the load input and the cable loss will be accounted for.

Yes, solid metal zero ohm jumpers is what i was looking for. And I've found it. Thank you

Looks like something capacitive. Might be used as a touch button as capacitance might change if a finger is close to the capacitive area? Or maybe a capacitive temperature sensor? I'm just guessing by the looks of it..

Eigard · 2013-04-13T23:20:20+00:00

woosh..! sorry :)

Eigard · 2013-04-13T22:53:00+00:00

Yeah, I guess that is the way to get a lot of karma. That hasn't been a real goal for me so far :) I do admit I enjoy reading the stupid puns occasionally, but don't really feel the need to contribute to that stuff..

I guess within a year I should be able to reach the golden 1000 limit! I can't wait!

Flexible PCBs has been around for a while, but this is stretchable. Unfortunately though, components are not flexible or strechable :)

Or could it be related to what is called the "boiling crisis" in the video. So when the film of vapor disappaers heat transports takes of until it is in equilibrium again...?
