This is a No-Clean solder paste, therefore, it's intended not to be cleaned. If you need your assemblies to be cleaned post assembly, I would highly recommend a water soluble solder paste. It will provide much better looking boards in the long run.

Hi there , I agree with phil .. but we cannot change the architecture of the card to mount the connector on the 2nd side. Steve , we are producing large series, so we can't manually ship bond the connector .. for the moment, we cannot invest in a gl

OK, you can't glue, Pallet Guys pallets are out the door, dual line reflow prevents from any lower temp solder paste.... Do you have a 3D printer? Are there parts underneath the connector in question? Measure the PCB thickness, pint out a custom hold

Sebas, on your profile you have listed U2, U101, U102 and I was wondering if the questioned part is one of them. I attach a typical profile specs - you should follow the one for your paste. In the one you attached the slope is too fast, soak is prob

Hi Steve Thomas Effectively by IPC-610 standard specifies in the "content 8.2.13 Quad Flat Pack Plastic Package - Without Terminals (PQFN), Table 8-13, page 8-84" which depending on the class of manufacture notes 2-5 of the table, which in theory do

Sebas, some things in your profile don't make sense. 3 of your thermocouples, #1 # 4 and #6 are consistent. The others show completely different data. The consistent thermocouples, also, show peak temp at 241 - 243 degrees. That is extermely high for

Hi Nizar, Pick and Place nozzle, pick-up speed, component symmetry if it has to be rotated while picked up are just some things I would look at. See also if the trays you pick connectors up from, are programmed correctly to the machine. You can al

Hi Nizar, Would you consider having maybe separate nozzles for two separate connectors? If they are different in size, you might have a problem there, since the nozzle you use, is only good for the one you get the nozzle for. After that, I assume yo

Just by looking at your attachment and seeing that error, I would say that you didn't put in the magic word when you reloaded your software or mistyped it if you did. If you don't have your magic word you will need to contact mydata or whoever you bo
