Hi techies,
I received a board sample that probably we could assembly here, but I had
one doubt about the manufacturing process.
The board is a VGA card and has trough hole and SMD components at top side
and 2 QFP 100 at bottom side. The 2 QFP had no glue attaching the components
and were not soldered by solder wave machine, but all trough hole components
were soldered.
The question is :
The 2 QFP were covered with solder mask and passed to the solder wave
machine ? Or they used selective solder to avoid contact with the 2 QFP ? Or
there are other ways to assembly this kind of board ?
I am trying to figure out how they assembly this board, I am not familiar
with this kind of assembly.
Any input will be apreciated.
Thanks
