Here's what we hear you saying:
* Trying to repair a printed circuit board assembly
* There's a problem replacing a 57 pin, 20 thou connector
* Can't get enough solder paste on the connector leads
* Printing paste, replacing the connector, then reflowing the assembly

If so, try either:
* Open up the apertures of your stencil ... OR
* Use a thicker stencil ... OR
* In addition to what you're presently doing, use a manual paste dispense gun to lay a line of paste over the connector leads. Then reflow

If not, give us more detail
