Thanks Dave. What you say makes complete sense. We ran a job a short while back in this way (though without bonding) and found we had a much higher than normal failure of the BGAs which I can only attribute to the secondary reflow. As I have only got

joanne please pay attention, each heavy no-clean flux residues not completely heated due to hand soldering becomes a moisture absorbing conductive pathway, causing electrical leakage. So I suggest you to clean well the board after hand soldering or

Hi davef, Thanks for the suggestion. I have inspected the heaters but I think they are OK (no visible coating, deposits, etc.). Unfortunately, I'm not sure that the residues are ionic. It was just preliminary report of the person responsible for the

We have yet had the need to use local fids on our boards you must be putting down pretty fine pitch parts that are needing the acurcey if it is failing fids that are within the search area then maybe its somthing else size our lighting it should fin

Hi Rajeshmara, Mail sent with the datasheet of the glue we use in production. Thanks for first information you provide me for the shear specifications on 1206. But can you be more precise on this point ? How did you define it ? Is anyone have more

The AQ400 Series (manufactured between 1992 and 1996 used a Myron-L brand resistivity controller. If you purchased this machine from Aqueous Technologies you would have received a Myron-L manual which describes the calibration procedure in detail.
