ACI offers solderability restoration services by using Reduced Oxide Soldering Activation (ROSA) technology to remove the oxide layers from circuit boards or components and then re-tin or otherwise coat them to maintain a solderable surface. The R

Cristiano, Are your oxidised components now all on boards ? How many and how many terminations ? If you have any that are still to be used, maybe you can get the supplier / customer to replace them, unless of course they are well old. If you have

What�s the best storage method in controlling SMT parts ? Currently we get all the parts from our stores for certain jobs and stock them in our Reel Racks with their designated part numbers. When they�re in SMT area they all get mixed up with some of

We are currently evaluating a "selective soldering machine" from Ersa. We have been using it for about a month or so now and have found it to be very useful on "difficult to wave solder spots", but it is not as fast as a wave soldering machine. It mi

John , I had some experience of selective solder in a high throughput environment and though the quality of s/s was good , the throughput was not . So if throughput is an issue , forget it . I would go with the hand-solder option , although as has be

We see this type of problem with a couple of our boards. It has proven to be a problem with the board. During manufacture at the board house the thru holes for the connectors are plated a little too heavy causing a smaller hole. If you haven't alread

There is a variation on the pins that come through on the other side. The pins that are deforming are roughly half the size of those which aren't deformed.There are no witness marks on the pins that are deformed, suggesting that the pins aren't fouli

Bingo! Sounds like you solved your mystery. You've checked your key process steps, the product has been running in your processes for some time with no process changes. This all points back to one of your process input, i.e. the fab. Experience s

I love this!!! Two whizzettes with the same information and they spin-off in two different directions. Gad this is great!!! Delamination is a pretty broad topic, but that you have a problem with two suppliers makes me think the delamination is cau

Hi Guys, I'm sorry to ask you this, but I got mixed infos from the archive. I want to define a process in wave soldering regarding bd-wave interaction. Now "What's the required dwell Time of a lead in the solder bath?" Some says 3-5 secs is good, som
