Surprise, surprise. ;) Wouldn't think of it.... Yep. I'm not as concerned about two flux chemistries mixing and causing a substrate China syndrome as I am about the OA flux retained in voids and subsequently released in a touchup operation. If w

Hi, Our engineering board has to decide which technology is better for the hand soldering of the SMT components: HASL or Chemical Ni-Au. We have an automatic line for SMD assembling and our experience shows us that for this automatic line is better

If you do not have one of the big in-line aqueous cleaners, then there is an easier way that is a lot less expensive. I suggest you try Asahi's AK-225T vapor degreasing solvent which has been around for 10 years now. And it is legal. If you have

Hi Dave, Good to "talk" to ya again!! I have attached a photo of the antenna. Hopefully it will work its way through the system. The pictured antenna meets all our criteria. The defective antennae all seem to slide toward the center of the PCB (

Good to talk with you too. Oh, just the way I had it pictured!!! Yeh, right!!! [http://davesmt.50megs.com/pictures select kristenna.jpg ] Which part of the antenna "sees" heat first [Are all legs (vertical part), two legs, or one leg of the anten

We have both CP 4/2's and 4/3. We're also running Siemens S20's & F4's. The 4/3's vision is more temperamental and slightly harder to program. Machine startup and nozzle centering takes longer, but placement time is slightly better. Honestly, for wha

I have to say I agree with Dave. The experience in Oz is that OEM's that dabble with EMS tend to go broke. The ones that do survive tend to have big brothers with deep pockets to get them over their lean periods but even they will only put up with so

What type of preheaters do you have on you're wave? I have to agree with Dave. Your leads are not cold, they are hotter than the annular ring on the PCB. This would cause the solder to go to the lead only rather than the component and land pad / a

Hello Paul, Without all of the specific details of your product I would recommend providing the BOMs and samples to a couple of vendors and have them prove their capabilities. The Siplace platform is a solid platform for your application and the ap
