First Coop Boards

[Jeffl]

I checked the last 5 I have and 4 are to tight to fit.  One slipped right in.  The ones that are tight don't look like they are nothing I can't fix.

I think I need a 1.5 mm drill bit as the post size is 1.3 mm.

of the two in this coop, one was tight, the other was perfect.
Separating the blocks helped, as did a touch of sand paper on the leads helped ease them in.

Both boards I just received are very tight. looks like some sanding might do the trick.

So far the first 3 boards ( 3 left to do) have had very tight terminal holes.  I have started "gently" beating smaller sections into place with a rubber handled screwdriver instead of placing the whole line in at once.  It is a little disconcerting watching me beat on an LE, but everything still seemed to work when I go done soldering.

I am sure I can get some replacement pcbs in a few weeks for anyone that has not put their parts on and finds this to be the case hold up and pm me let me know I need to know how many we are talking about that need replacement before I can do anything. There were no change to the pcb so while they are research the issue it will come down to a mislocated bit in the drilling machine autoloader carosel I would imagine.

Just checked out the 10 I received.

2 are tight, not going to be a problem.
8 drop right in.

The 2 that are tight, look like the plating is thicker, all holes a little smaller, and 1 via is full.

Have fun

RJ -  What should the finished hole diameter be for these 32 holes?

[LightUpMA]

Mine were tight but after some coaxing they went in begrudgingly.

The 2 boards I have issues with I can get the connectors in partially.  There are holes that are just too narrow; not all holes mind you.  It seems to be about 1/2 of them.  The bad ones I can't even pass a #59 drill bit through without forcing.  I don't think it is a lot of extra solder mind you; just enough to make a challenge.  Eventually have been able to slowly wear away the solder enough to get the connectors on one of the boards.  Still working with the second one!  Can't send back as I put the parts on already!

I help someone yesterday building there first LE and saw the problem. Seems the PCB house might have over plated the board and also the tolerance of the holes size might be a little to close and not allow any excessive over plating which can happen sometimes.

It is tight, maybe RJ can specify a slightly larger drill hole size for the connector strips.

Hmmm, not going to make any tight jokes, but that's the way I like it!!!!

The tolerance for the holes was done this way on purpose to prevent the terminal strips from falling out when users were soldering them in.  I have been here for years and this is the first time I have ever seen this happen.  I wouldn't be to quick to suggest making changes to the board.

I agree,
 the only thing that needs to change is quality control on the end of the board makers.

1 of the 2 I received in the coop were this way.  I managed to get it together by separating them and putting them one at a time after slightly reaming the holes that were tight.  Everything tested OK when I finished.
