Board Rebuild...

[Paul]

So - A thread probably best for the likes of @lukewells and @Nedreud

So... I have this that i need to populate...



So - Question - I have built many boards before, so no issues there, however, any tips with regards to the easiest way to start from scratch... i.e. Resistors first, then sockets, then TIP141's, then caps etc etc....

Just wondered which way you guys would do it... (everyone seems to do it their own way!)

Cheers

Usual way is to work vertically.

Ie... put in the lower profile stuff first.

My thoughts... unless the "pro's" have any advice to the contrary

 

[lukewells]

As above, start with the lowest stuff first. You can get some semi-rigid foam that they use in pcb assembly fixtures and what you do is add a layer of components, clamp the foam on and then you can turn the board over and solder the components in without them falling out, or without you having to bend the leads to keep them in place

 

[Paul]

Semi rigid foam used in PCB assembly?? Sounds like a good idea, however never heard of it!

 

[Spandangler]

Ah yeah Paul. If you type semi rigid foam for PCB repair into google, it's top of the list mate

 

[Nedreud]

Agree with previous comments. Start with components that sit lowest and closest to the board, so usually resistors, diodes. Then maybe DIL sockets and eventually moving on to capacitors and transistors, and finally hardware, e.g., sockets, fuse holders.

Make sure before you start to clean the solder pads thoroughly. I usually wash with Fairy, rinse and dry, then use either a fibre glass pencil or 2500 grit wet'n'dry to very gently clean the pads, then wipe with alcohol. Just makes the solder flow smoothly so you need less heating time which is less likely to damage parts.

What are you building anyway?

 

[RudeDogg1]

Something for jolly park me thinks

 

[replicas]

Rather you than me buddy. That looks a mighty tough one to complete.

 

[lukewells]

I've got a blank one of these to build up when I have a spare thousand hours

They are $1000-$1500 to buy complete, so cheaper to make one from scratch

 

[replicas]

Good luck with that.

And as if you aren't busy enough.

What is this Google of which you speak?

 

[Spandangler]

I think it's a hardcore porn site. At least that's what it always shows me!!

 

[Paul]

Yup - Jolly park driver board - you never know it might make it out of the shed sometime this year.... and then i need to start/finish refurbishing it...!!

@lukewells - You would be proud..... ........



Just a relay, some headers and two caps to get (missed from my order - caps because I didn't know they were there as weren't on the cct diagrams!!) and it's done

 

[replicas]

Sweet !!!!!!!!!!!!!!!!!!!!!!!!!!

 

[abaxas]

Come on... tell all.

How many times did you check the orientation of the diodes

 

[Paul]

Come on... tell all.

How many times did you check the orientation of the diodes

I do every single time i look at the board

Meant to say - Almost finished, other than moving the relay over...

 

[Carl Spiby]

Nice job.

 

[RudeDogg1]

A job well done paul
