Hi Stefano, Although your concept of Wave soldering such devices is possible, I would look at an alternate solution. An easier way would be to Reflow solder all Bottom side SMD components with solder paste, followed by wave soldering for only through

Hi Andrzej, I guess you mean peelable solder resist. Good idea to try during R&D, but certainly not a solution on production floor. Also, few constraints to be considered such as presence of entrapped air between component and solder resist, the natu

Hi Simon, The main reason that it would probably be removed would be do to lack of clearance for a soldermask dam from pad to pad. typically if the clearance from pad to pad is under .008 the solder mask dam would be removed. Min recomended dam siz

I've done it many times in the past and I would never recommend to do something like that. always you will have troubles with quality, unless the board is really easy. 3 good persons can do it in 2 days. One create programs and trouble shoot all th

I'd agree. I wouldn't be able to turn significant volume in that short a time span....but, then again, I don't see a lot of people that need significant volumes in that sort of time span. And, agreed on turn-key. I've done a couple of tk jobs in t

I am assuming that the card that was changed was the motor driver card. Did they change the card with a known good board or just swap the X and Y cards. If they swapped cards it appears that the card that is now in the X motor slot is bad. Open the a

We currently use Unisoft on a limited basis. It was purchased as a low cost solution to track a specific product until we can roll out a more robust tracking package. We are currently moving towards Optimal Electronics. I think their quality package

I am attempting to identify a good epoxy to hold on larger parts on thru the reflow process for the opposite side. We currently dispense epoxy prior to second reflow on the corners of the component because the epoxy we use cures before reflow and doe

In BIG-boy, high vibration applications to secure large components, we've used 3M #2214 structural adhesive [One part, 250*F (121*C) curing 100% solids, paste consistency epoxy adhesives designed for bonding metals and many high temperature plastics
