Sounds like the Pin in Paste would be a reflow technique not involving a pot. I'm guessing however the same causes are in play, in that the poorer wetting of the Pb-free allow means it drops out of the joint before it can wet to the terminal. We us

You also need to get with the PCB manufacturer. Their is a lot that can go wrong with that many layers. If the manufacture is trapping that much moisture. you may have a hard time baking it out. Dave and Graham are right about the time and energy. It

Vapor soldering has some advantages for heavy boards, especially in energy transfer to the board and solder. The soldering temperature is fixed by the boiling point of the liquid used, and will not exceed that temperature, another advantage. The tr

What equipment do you have? As well as the comments from others, another major influencing factor can be the residual heat in your PCB carrier. It takes more heat energy to warm a cold carrier than if it is already hot from the last cycle run. This

In general, smaller objects heat up faster than larger objects because they are lower mass. For example if you heat up one liter of water in pan and two liters of water in another pan with the same heat energy applied, the smaller mass will heat up f

If N2 is not an option, the cut wire feeder or drilled wire are your best bet for now. You need to optimize wire feed rate as well. The solder joint on the robot takes about the same time to form as in manual soldering. If you need to speed the solde

It is a feature we could use, but mostly I turn it on when I have stuff to go through and set it to cooldown when I'm done. We don't run inline so I can buffer a rack or 2 of PCBs if I want to maximise energy efficiency. Warmup time is really good at

What exactly counts as "always on"? Our ROHS wave solder machine is always on during the week but the pot shuts off at the end of the shift and turns on early in the morning so that the solder is melted before we get to work. It is only using a small

A transformer winding machine is a specialized piece of equipment used in the manufacturing of transformers. Transformers are electrical devices that transfer electrical energy between two or more circuits through electromagnetic induction. They cons

Hi! In the course of study, every student faces the fact that the number of written projects seems immense, and there is not enough energy for everything. In such situations it is worth paying attention to the service https://domyessay.com/write-my-c
