What are my options for packaging a WLCSP IC as a DIP?
Many board fab companies have in-house assembly capabilities.  We have done this with the &quot;carrier board&quot; or &quot;breakout board&quot; approach as mentioned above using a board house to do both board fabrication and assembly of the part onto the board.  We paid $25.30 for each finished assembly at quantity 200 (the part in question was $8 at this quantity).  There was a lot charge of $250 and a non-recurring engineering charge of $775.  We employed a high-temperature solder to hold the parts on the board.  The NRE is a one-time charge unless the design is changed, but the lot charge is the same every order with a 200-piece minimum.  We put the legs on ourselves after getting them from the board house.
