The problem is there wasn't any reflow when the board went through on the bottom side. Even if they didn't fall off becuase the temp was set low enough, while running the top side, the fact still remains that there wasn't reflow on the PCB pads to be

We have a board that uses 0402x4 RNET packages that we are having a difficult time getting to solder consistently. Paste deposition is fine (using AIM WS353) and profile is dead-nuts. I'm starting to wonder if this is something that we're just goin

Out of curiosity, what is your top side peak temp @ reflow? Have you inspected the boards prior to SMT (at your 5DX machine?) Also, have you tried to run the board through reflow with out any parts or bga placed and inspected? I how long are you in
