After 16 years in the industry, I have honestly never heard of putting wax in a solder pot. Anyway, I do have some experience with Treiber wave solder machines, and as I recall, the air-driven pumps are a nightmare to service. First of all, make su

You stated that you are producing Class 3 boards so I assume you are familiar with the IPC standards.To answer your question directly, I'll refer you back to the J-STD-001. Clause 12.1 states "12.1 Rework Hardware defects shall [N1N2D3] be documented

Been awhile.... We are in the process of determining where are gaps are for compliance to J-STD-001E and I have a question for those in the know. This section of the standard says the following: ----------- Electronic/mechanical components (includi

We have two ZipaTec 460s Selective Solder Machines, one for Lead and one for Lead-Free. This morning we noticed the solder pot was covered in solder balls, and after asking the operator what they had run, the answer was "Nothing." The operator had al

I remembered something from the TechNet a long time ago about heating the board with a heat gun to see if the white spots disappear. I searched the archives and found this from Bill Kenyon: Quick identification of solder mask white spots- if it is t

What type of flux is in your solder paste? Active or No-Clean? With lead free solder you really should be using an active flux. The lead free oxidizes during reflow if you are not using a Nitrogen or Vapor Phase reflow. So a more robust and activ

Excellent X-ray picture, very helpful! It looks like you have a lot of voiding on the center thermal pad. My guess is that outgassing is pushing solder off the pad which is forming solder balls outside the body of the component package. The first

If the world was a perfect place, I would recommend preventing solder balls in the first place. While low amounts of solder balls are common, a high volume of solder balls are problematic to a cleaning machine (batch or inline). Solder balls may beco

I want to avoid peoples preferences as they will differ and will not be a deciding factor. A heat gun will introduce risk to surrounding PTH components and having to add protection for those, will limit any gain in productivity. There is no question

If you add any "flux cored" wire solder to the pot make sure you have ventilation as the flux will burn off and smoke like crazy. This solder pot is like any used in a wave or selective solder, no flux. The flux is added to wire prior to di
