Matt solder mask finishes gives the widest process window in view of potential amount of residues when using No-Clean. Shiny (glass like) finishes are more sensitive to residues due to lower surface area compared to matt finish. If the shiny finish i

That's where this website falls short. Sorry to b*tch, but there's lots of people who post here whose primary language is NOT english, and you know what they say... "a picture is worth a thousand words." Original Poster guy...try "Image Shack" to s

Where are the shorts occurring on the 96 pin connector? Are they consistently in the same areas? It looks as though there are a number of pins connected by traces on the board, and/or the ground plane. This would cause a lot of repeatable shorts i

Not as such. Choices are: 1 Cut and epoxy some board foil from your board fabricator. 2 Sacrifice part a pad repair kits from the likes of: * Engineering Lab 905-785-1982 * Circuit Technology Center 978-374-5000 * General assembly suppliers catalog

We have been seeing continued difficulty with solder shorts and/or insufficient barrel fill with our Juki selective solder machine while using SAC305. We want to switch to something in the SN100 series, but we do not know enough to seperate the hype

Hi, I have just taken a look at the Connector Images. Is there a difference in pitch between both connectors ? From the photo it looks like the Annular Rings are oversized on Image #1 especially around the centre area ( this might be the image ).

You're joking rite? I mean the pitch between these two connectors is night and day. Of course you will get shorts on the 96 pin connector because your leads are right on top of each other. Now, what to do about it: You took a picture of the top o

Check cure of solder resist. Use a No clean low solids rosin flux this will stop problem. Should see almost zero solder balls if put through a single wave compared to a dual wave. If this is true then it is a resist issue and cannot 'resist' the sold

Omid, No-clean fluxes need to be used right out of the can without thinning. In the past with RA and RMA fluxes you could adjust or thin them to your desired density because they had plenty of solids up to 30%. No-Clean fluxes have a lot lower solid
