I have seen a method used where the pins on the connector are of the same materials as the thermocouple and the connector is connected via single strand wires of the same material to the PCB however the wires were spot welded to bare copper pads to r

Also try monitoring your temperature profile with a temp sensor independent of the machine, maybe your heating element isn't spiking quite as well as it used to ? sarason

Now that I've seen the pics... Soldering could work just fine. If you are going for large production then you could get copper discs cut and mounted in tape carrier ($$). This would make it very easy for automated equipment to assemble. Mounting a

It is usually done differently. Sensor is in the solder. Once solder becomes goes below the sensor, it triggers you need to add. I believe it measures temperature rather than distance.

It's possible that there is limited application of "3M™ XYZ-Axis Electrically Conductive Adhesive Transfer Tape 9719" similar to your intended use. What do 3M™ application types say? Certainly high temperature soldering would make a mess of a piezoc

The 300 degrees is the temperature as measured at the sensor. The actual air temperature just above your PCB may actually be much less. If the oven is properly calibrated then the 300 should represent air temperature at the board but I have seen ma

That was the case with your oven but it is not so with ours. First, the distance from walls of the inner chamber to the product differs from one oven to another. Second, the dissipation of heat from metal heats up the air in the oven which in turn h

Vapor phase soldering systems by Asscon are characterized by special designed heating modules. The thermal mass of the heating modules is designed so that a completely delay-less and direct regulation of the heat/flow/energy transfer to the soldering

How do you know that "approx 450�C" is "too high"? As a side, the temperature on the temperature sensor is: * Inaccurate. * Not the temperature at the solder. Listen, operators are smart people. They have figured-out that they can solder faster wi

Thanks, We currently use Metcals for our regular work and I was looking at the ERSA system for the BGA rework. From what I have seen it seems simple to use, and since it uses IR you don�t need all the attachments for different size BGA�s. You just
