I used method 'A' but I leave the wave on. I use a stainless steal brush like 7248T13 on McMaster-Carr.com. This way I can apply the acid and scrub the nozzle. Another important part is get a small brush to push down into the nozzle to make sure y

It's a four-spindle head. I've already learned the joys of the size of the nozzles...on a job that had an 0603 cap a bit too close to an SOIC. The first panel ran, and the cap placed after the IC...and I had parts everywhere. Got it figured out an

It's difficult to tell anything from your picture. But playing the odds, I'd say it's not "gold corrosion." It is very difficult to corrode gold. Gold is a NOBLE metal. From Wikipedia, the free encyclopedia In chemistry, the noble metals are metals

We bought a conformal coating removal machine AKA a sand blaster at an auction. It is a CCR2000 especially made to be ESD safe. Does anyone have any experience with sandblasting conformal coating? We mostly use humiseal 1A33 and UV40. When we use the

Try Sandflex Blocks for polishing. These will polish but not scratch the gold. See: https://www.amazon.com/Sandflex-Sanding-Block-3-Pack/dp/B000GACU1Q/ref=pd_bxgy_img_3/143-4402992-3496538?_encoding=UTF8&pd_rd_i=B000GACU1Q&pd_rd_r=7be0b73a-dd71-4bc

Dross removal is dependent upon the "activity" in your solder pot and the usage of a inert or an "air" atmosphere. The more moving that agitate the solder, the more dross. Basics first and then the answers will make sense. What is dross? Oxidatio

I don't think I can post pics in this (if anyone knows otherwise let me know), so I will email them to anyone who's curious. Here's the answers to your questions: Placement Force: 0201s are placed on the Siemens S23s with 1 newton of force. The s

Hi Randy, From a bare board manufacturers stand point, scoring is probably faster and easier but has limitations. If your boards are square or rectangle scoring will work fine. Once assembled the scored grooves can be sliced apart using what is some

If the terminations on your components are not barrier plated, you must be very careful about the amount of time you stay above liquidous. As you'd expect, longer is not better. The longer you stay at liquidous, the more of the component terminatio

Allow me to re-state my response. Hours on an oven would be the last thing I would care about if I wanted to know something about it. There is no standard lifespan on heaters, blowers and the like. They can last a year or ten. Sure you can assume a 5
