Yes!!! How can we assemble boards with 20 pitch when we allow 0.008� error to the master art? Excellent question!!! IPC-D-300G has nothing to do with assembler requirements. It is written by and for fabricators, so that they can be comfortable.

What is the recommended board finish for 0402s? Is HASL good enough or is Ni/Au better? Thanks

We once used a padded mesh in our board washer baskets to prevent damage to components. Can anyone tell me where I can find this material? Thanks

Are you running any type of vibratory wave on the Vitronics as opposed to the electrovert? How about any turbulent wave differences if any? The only time I have ever flooded boards in fixtures is when the seal is broken or run an excess amount of v

We are using HASL board for Press Fit, without problem in the past until recently. Now we are seeing the solder in the PTH melt and block partially the PTH hole during the reflow. It gives problem when Press Fit. Anyone has advice on this?

We currently have two 9700 Emulsonator board cleaners, would like to chat with others who are having problems with flooding, controller problems and have done the controller upgrade. Thanks

Floyd, Purchase a spare set of motherboards, get the numbers from the boards and google them up. The CP-40 motherboard is getting on now so you should pick up new ones very cheap. Also don't forget to check the battery on the motherboard.

Questions are: * Do the BGA pads on the board take solder when you solder them by hand? * What is the temperature on the BGA pads during reflow? * What is the temperature on the other component pads during reflow?
