5v relay PCB?

[Willabe]

Does any one know where to buy (in the USA) a good quality PCB for a 5v relay? No molex connectors or headers, no 5v regulator.

Just a small simple PCB that I can solder in a 16 pin socket for the relays Doug sells.

I can do it like Doug shows in his library, with turrets but a good PCB would be easier.

I look on the net but couldn't find one.


                      Thanks,    Brad

You talkin about a piece of Vector-board?

It wouldn't be hard to design an actual PCB designed to hold a DIP16 socket, a diode, and 8 turrets with 4 mounting holes.  Once you get past setup charges, it'd cheap cheap cheap to reproduce.

Hi Richard,

Thanks but no, not a perf board, a real PCB.

I figure with all the guys out there that are into building tube amps some one would have made them already and has them for sale?

Like you say it's not a hard board to make and would be cheap.


              Thanks,        Brad

 Without saying the forum in question, I'll just say you might see if the guy's building D#mbles might have something like that, haven't seen one but then again I wasn't looking for one particularly. They'd be real likely to have something like that with all the relays they use in those amps.

Regards,

Don

Thanks Rev D, I'll take a look see.

Thanks DL, I did find the kit boards, but I don't think their for the 16 pin dip sockets that Doug sells?

Last night I did find the second ones that you posted . I belive those are the right size for the 16 pin sockets. But $10 a piece seems a bit pricey? I was thinking under $5 each.

Just go to RadioShack...

Dual General-Purpose IC PC Board
Model: 276-159 | Catalog #: 276-159
$2.19

Hey, now that might work. Thanks sluchey.

That RS board Steve pointed out is great

Get that

'You can even break the traces between the center dip area and outside solder pads and run parts across the gap

[Willabe]

Well I bought 1, well you get 2 for $2.19 (+ tax), looks very workable. It's not a plated through hole for the solder pads, but if I solder in the 16 pin dip socket (incase I need to change it) it should be fine. Dougs right you have extra pads for the diode, wires, etc.

I think I might even cut off part of the (unneeded) board, which would bring it down to, 1-3/4' x 1-1/4", from 1-3/4" square.


                       Thanks guys,     Brad

i have interest in a 16 DIP relay PWB as well, so i laid one out.

the design guidelines:

* use dougs 3/32" turrets.
* DPDT relay that doug sells.
* use mill-max sockets.
* try for under 2" x 2" board dims. we have 2" x 1.5" with 1.5" x .75" mounting centers.
* 4 post mounting utilizing 4-40 fasteners.

in order for us to use dougs turrets, we must specify 125mil thickness PCB material and this drives the cost up considerably - about 2x that of 62mil or 93mil material.

hole finish tolerance is usually around +/- 5mils and varies from mfg. to mfg., so you'll need to make allowances. i used a 94mil hole for the turrets - the turrets fit into a 3/32" hole which is a 93.75mil hole so it's gonna be close if you stick with the pattern presented. you may wish to specify a #40 or #41 hole size for the turrets if you want a for_sure_fit. better still would be to leave the board un-plated (no tin/solder finish) and just have a solder mask over raw copper with unfinished vias. it's trial and error based on the board house tooling, etc.. get a couple made, test fit, adjust if needed, accept or repeat, then order quantity. if you change board mfg. then the tolerances will change.

the easy way out - make hole 5mils overbore, then stake and solder - worst case is turrets swim in 10mils of air slop; best case turrets fit like a glove. no worries because solder keeps things tight.

if cost is an issue, specify 62mil PCB material, no solder mask, no silk-screen, no plating, and use dougs 1/8" eyelets for 1/16" PCB material thickness.

PM me if you are a member and would like a copy the gerber RS274X files and NC drill file.

Thanks a lot for the info, Dummyload! I'm still afraid I wouldn't have the confidence to know what to do with it...

Let's just convince Doug to make/sell these :). Doug? I exclusively buy my boards from you already and would buy a butt load if they were not too pricey.

The problem seems to be for most builders wanting to use relays is just having a place to physically mount them. I think any ol' board would do. Those Rat shack ones are just so big and ugly - really mess up my amps' vibe!!
