It's always interesting to learn about the different jobs within an electronics manufacturing job shop. By understanding all the roles that exist to ensure our small batch electronics are properly assembled gives an even better look into the exciting world of electronics manufacturing. As a part of my in-depth blog series interviewing those working on the technical side of things, I had a chance to chat with Cathie Johnson, an RBB Selective Soldering Technician.
Can You Tell Me About Your Electronics Background?
Walk Me Through a Normal Day of Work at RBB:
In addition to running the selective solder machine I also do first piece inspection, and help out help in testing and shipping when needed. Currently, I am also training in SMT, and the Axial Insert Machine!
How Long Have You Been Using the Selective Solder?
I’ve been on the selective solder machine for a little over two years. Within that time, I have been able to learn and have got the machine down, when a problem arises; I have a good sense of where to look to make a change and continue on, spending a very short amount of productive time.
What does the Selective Solder Do Exactly?
The machine reduces the need for wave pallets, which can be expensive, for bottom side SMT components, and reduces the time needed for masking, which can be costly. I program the machine to go around SMT components, and mounting holes or open barrels. This can help us avoid the masking process all together. It also helps with parts that can’t go through the wave; such as those that cannot be washed or overhang the board's edges. It also reduces the amount of hand soldering that needs to be done. In addition to making it easier and faster for the build, I also use the machine for some rework, which can be challenging and time consuming.
What Would Be Your Top 5 Tips for Using a Selective Solder?
- Make sure that the right solder pot and accessories are being used.
- Watch the machine as it runs. Board damage and rework can be minimized if they are caught early in the process.
- Prevent boards that are warped or bowed. This will cause major problems when you’re running them.
- Watch for lead length! Varying lead lengths can be tricky and cause dragging or other problems.
- Make sure the parts are inserted following polarity correctly. (Helps reduce rework.)
What's Your Favorite Part About Using the Selective Solder?
My favorite part about using the Selective Solder machine is that on a daily basis, I am pretty much my own boss. I can control the machine to do what I tell it to, and I get to challenge myself every day.
