Dear Technetters,
We are going to be assembling some lead-free 1.6x0.8 mm micro BGAs with
0.5mm pitch and 0.17mm dia board pads. Anybody else have experience with
this small a package?....I am concerned that there won't be sufficient
flux in the tiny solder deposit to clean the oxides during reflow,
leading to graping and/or head in pillow situation. Do I need a dip
fluxer for the part to do a flux only attachment, or to augment the
amount of flux in the solderpaste-solder bump system? I am told I have
no time to do DOEs to determine stencil and reflow parameters, so I am
turning to technet for help.....any thoughts?
Regards,
Amol
