By dispensing no-flow underfill onto CSP pads, then placing the CSP and reflowing, the flux in no-flow underfill will clean the oxide, solder will wet the pad and form a joint, and the underfill cure will be completed at the end of reflow cycle.
The steps involve applying solder paste, placing components on the PCB, and reflowing solder in a conveyor oven.
the scars, physical and mental, of reflowing convection/IR ovens.

However, if reflowing under air, soaking at around 200[degrees]C for Pb-free reflow will result in much more severe oxidation on parts and paste than soaking at the typical 160[degrees]C for SnPb reflow.
(Higher [DELTA]t assembly designs can be reflowed in air at up to 260[degrees]C.) The difference provides a safety margin when reflowing temperature-sensitive components.
This thermally protects surrounding components, and keeps a bottom-side component opposite the top-side component being removed from reflowing. Boards often have two BGAs back-to-back, but only one needs to be removed.
Reflowing in a convection oven is a very unexciting process: The assembly disappears down a dark tunnel and emerges about four minutes later.
Using visual feedback, x-ray data, equipment heat and airflow indicators and thermocouple information, we determine if we have succeeded in properly reflowing the BGA.
