If you are doing X-Ray post place and pre-reflow you should be good. Look elsewhere. Check profile - full lead free or hybrid? Be sure you are acheiving the required reflow temps and TAL required for the solder paste too. Check for belt movement

Bill, Any reflow oven sales guy would be happy to help you with a snazzy sales pitch. I also had some info from paste manufacturers when I pitched it to my boss. Essentially, I believe, it comes down to control. You may be able to get a 4-zone ho

Lead Free profiles can be achieved on 4 zone ovens on relatively simple boards (I did this for a year). The 4 zones can be a bear to get right for a really optimum profile. Assemblies with significant Delta T designs can be nearly impossible with 4

How big is the cap ? We successfully reflow caps that measure aprrox .750" x 750" at the base and are .678" tall. The ovens we use are Vitronics XPM's.(1230,1040 and 930) We also process these caps through our Omniflow 10. As stated, oven length wi

I have an issue where our production team has ran the wrong reflow profile on a no lead product where Indium NC SMQ-230 no lead paste has been used. You can still see the grains of solder after reflow. What I am look for is if anyone has any recomm

I have a problem in my Lead Free smt production line,i run BGA product for the first time. The product consist BGA and Connectors. If i increase temperature in Reflow Oven it will be melting the Connector, but when i decrease the temp. BGA become raw

With oven temps rising due to Lead-Free Processing, I'm looking for some information on high temp Reflow Oven lubricants. I've found some info in the Fine SMTnet Archives on Chain Lubricants, (Mostly Synthetic Motor Oils), but I'm wondering what othe

This has been a challenge for most manufacturers. It depends on board thickness, lead or lead free paste/parts. We have a slim-kic to get the profiles correct in our 14 zone oven. I believe it may be the recently posted suggestion of too much heat in

We have been running a Heller 1707EXL for 8 years and added a Heller 1707MKIII about 1 years ago. We have not had any problems with either one of them. We do both lead and lead-free assemblies along with BGA/LGA components. If speed/volume is not

Would you be able to post an image of the joint in concern? Sounds a good problem to resolve. Guessing you have used an external profiler & not the oven built in type? If 100% certain the profile is correct I would focus on the paste from my exper
