Therefore, please approve our product specifications or transact the approval sheet for product specifications before ordering. 274 ! Caution Inverting the PCB Make sure not to impose any abnormal mechanical shocks to the PCB. 4. Optimum Solder Amount for Reflow Soldering 4-1. Overly thick application of solder paste results in a excessive solder fillet height. This makes the chip more susceptible to mechanical and thermal stress on the board and may cause the chips to crack. 4-2. Too little solder paste results in a lack of adhesive strength on the termination, which may result in chips breaking loose from the PCB. 4-3. Please confirm that solder has been applied smoothly to the termination. <Applicable to NFM Series> Continued from the preceding page.
