Installing Flash LEDs on Flex
Recommendations on soldering and bending processes when components are mounted on a flex circuit.
Pb-Free Soldering Profiles
Processes and Their Parameters
Although many important aspects required to establish the “ultimate” profile for wave or reflow soldering have not yet been investigated, several can be used as a starting point.
Use of Closed-Loop Process Controls in Dispensing
Tests show that a two-component epoxy adhesive will change in viscosity over time and cause a direct change in the amount being deposited. Yet a simple weight measurement can be used to calibrate a dispensing process.
Low Pressure Molding: A Primer
Low pressure molding reduces the process steps required by conventional potting techniques and is now in use for complete encapsulation of PCBs.
