CN, I forgot a couple things. The DEK printers are easy to program at about 3-5 min. The MPM is a little more difficult to program and it takes about 20-30 min. Resale value is also in DEKs favor. Just look around in the equipment section and see all

We've always been MpM so no comparison from me on DEK. All I can say is we have had 3000 series that seemed to need constant attention and almost daily wrenching. We got a couple of AP25 HiE's and they are easier to use, way more reliable and simpl

We run Dek ELAs and MPM UP1500, Everyone here prefers the Deks. Set up, software, maintenance, operation etc. There's not a lot in it - the guys just prefer the Deks. However we are an OEM and so get control on board design, finish, fiducials etc. So

I'm with Chunks on this. In my experience MPM's are very accurate and reliable. There are so many out there because people like them. You can make a program with 2D inspection in about 10 minutes. Things do sometimes break on the 3000's, but not

Unfortunately, I don't have a copy of IPC-A-610 D on hand, however, I believe in IPC-610, this �floating height� between lead and pad has no maximum specification restriction. As long as there is no voiding, it is still acceptable for all 3 classes.

Mike, dude, I feel your pain. Hearing stories like this makes my blood boil! It's almost as ridiculous as a customer who told me to put more solder paste on a MELF component to overcome noise issues - he used more solder paste as antennas to overco

The Speedline Technologies- Electrovert AquaStorm 200 is one machine that can do the trick. You'll need the Chemical Isolation option for the RMA flux and you'll need a cleaning chemistry like what Zestron and Kyzen have. Yes, hi-density boards with

Hi, What is the different between Electroless Nickel / Immersion Gold (ENIG) and Immersion Au. Are they refer to the same finishing? We has been using the Gold thickness (0.00005 - 0.00013mm) , nicket (0.0025mm) for all Gold finishing brd (Immersio

Chunks, For our lead-free eval, we had the same problem with "charred looking" solder paste up the component termination of one of the smaller discretes, coupled with excessive solder balling...this smaller part did see peak temps in the 240 range -

At my last employer, we ran a number of tests to make a "Hybrid" profile work (same profile Joe lists) . It worked great for everything but BGAs. The problem (6 months ago) was using parts not rated for lead free reflow temps. As the market fills wit
