My experience with different size boards and pre-heaters. The perfect world (right?) you would saturate the complete pcb with bottom pre-heat. But it is difficult with repair and rework equipment, not to mention the expense and foot print of large pr

| Mornin! | | We just had vendor in here pitching a "low-temperature rework system" which was intriguing, but too expensive. He did get me to thinking though, beyond heating ceramic caps before hand-soldering them, it seems like it would be ad

"and dip it in your solder bath for 10-20 seconds." Do you pre-tin them first or just dip them in regular solder? "You can't talk to molten solder, but surfactant will listen." "Remember, we're all in this together."

Hi, Thanks for the info. The current process is a standard SMT hand soldering process. The time does not include cleaning, prepping and pre-tinning. Its just the time for the re-flow of one joint itself. We are waiting on some new tips to experimen

Hi Patrick, thanks for the response. I might add some more information - we succesfully soldered some boards with the same settings of belt speed, pre-heat temp. etc. This batch of boards differs from the previous in a way that they are 4-layer. May

The trick would be to externally pre-heat your Metal cavity to attain sufficient temperature and then to flow in solder. This would ensure proper solder distribution inside the cavity.

Hi Grant, You definitely have a pre-heat problem and not a flux problem. Pallets together with the BNC connectors put a large thermal demand on your pre-heating. 3 zones would be a good investment even with leaded solder due to the high thermal dema

Wire wheel works too. Pre tin the part. Hand solder after reflow. Or order good parts. I prefer the last one. Hows that for an answer?

Looking for some Recommendations for a Selective Solder machine. We currently have a KISS103 no pre heater. We are high mix low volume, so batch is most like best option. I have used Pilerhouse Jade MKII years ago. Wondering what other option pe

Wolfgang: You're correct, I've obviously goofed this up, somehow!!! (sound of scurrying in yellowed soldering notes) Let me try and find the source for this to redeem myself.
