Hello, usually you will place your themocouples on the most critical parts on your board. I would say, very big parts, very sensetive to the temperature parts, heavy parts, parts with big heat-sink.... The easiest way is to solder your thermocouple

Good Afternoon Duane, Surface tension should be adequate to hold the smaller BGA's during second side reflow. You will need to ensure that nothing comes in contact with the parts during reflow. I have added a chipbonder adheasive at the edge of some

The high thermal mass of metal core boards makes them difficult to heat with hot air convection heating or IR. So, edge heaters are used for effective heating of heavy core circuit boards. Hakko and VJ Electronix offer edge heaters. We imagine othe

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

Looking for advice on soldering lead free paste to a board with very heavy gold plating. I have learned from the Customer that this is HARD GOLD and that it is 10-20 Micro Inches Hard Gold over 100 Micro inches of Nickel. When we reflowed the solde

We want a dedicated machine because we have some concerns with SMT adhesive residue that is in the bath contaminating boards. We are getting pretty heavy into class 3 so everything has to be pretty much perfect. We run 2 shifts and have 5 lines so w

SWAG has it. Carriers for SMT are a great idea, especially to mitigate sag, and allow some savings in setup. Fixturing setup advantage: You could fixture everything to a fixed width, and eliminate rail setups throughout your lines. Trade off the f
