Hi Yngwie Have you got a reflow oven yet. If not, forget about complicated profiling with test runs or reflow trackers. We've got a nice oven with integrated temperature-feedback system. You build any profile you want and the oven will adjust its hea

IMO: Sanyo and Universal? maybe, maybe not would not make sense currently. UIC production is on a "reduced" schedule. To be introducing a new machine in manufacturing in these time would not be wise but who knows crazier things have happened. Conce

I'm seeing a definate pick up of activity levels in my business. Equipment is finally selling albeit at depressed prices. Unlike last year however when things were not selling AT ANY price. At least there are buyers now. The huge CM's will take a l

Just a couple of points in response. For the most part I agree with your point on technology transfer, unfortunately the US has been doing this for years. As for who would want these older machines and how could you make a profit off of them. There

China is way behind the technology curve and will be for some time. They're still soaking up all of the through hole and 10 year old chipshooters they can get their hands on. China is the latest flavor of the month for cheap labor just like Mexico wa

Does this PBGA have eutectic balls? If so and the PCB is HASL finish, or has solder on the lands from BGA removal, you may not have to apply solderpaste. Check with you flux supplier to see if they offer a NC "flux paste" product, otherwise I know Mu

The Flextac micro stencils I mentioned are not metal, but rather laser cut polymer, so not as easily damaged. As for cost, Even if you only re-use them 5 times and not the 10 that another company I know does, they only cost around �36 for a pack of t

Silkscreening is falling out of favor, as it should. SMT IC devices can have their "pin one" solder lands indicated by a round mark, like a fiducial or a "1" mark, both made from either the copper clad PWB material or silkscreened. I have seen some w

Steve, As a reason for cleaning no-clean flux res: Well, maybe some of Por's products / customers can live with NC flux res, while others cannot accept it. So, rather than running two fluxes Por finds it simpler to clean the NC flux res. For us,

Hi mates, just my 2cents worth... some folks (like us) have product runs that have BGA using no-clean, coupled that with Class3 IPC-A-610 specs, topped with aerospace/military customer defined specs. we end up cleaning NC with a degreaser machine w
