There was a board that I worked on with a SMT connector height of 11mm (solder side) which needed to be covered with solder fixture (wave pallet/carrier). This thickness of the fixture covering the SMT connector was about 1mm, hence, in total it added up to about 12mm. The board thickness was 4mm so I worked with supplier to enable the machine to pump a wave height of 16mm. The result was ok but I still believed that it was a very poor work done on the PCB layout design.

As Ted mentioned the dross was huge..waste..

Do study the machine specification.

You are probably going to be physically limited to 3/8th of an inch (0.375, 10mm). Most likely the wave dynamics to accomplish this will create a lot of dross.

Dear Technos,
 
What is the maximum height of the components on the solder side that will allow for using wave soldering masking fixtures?
 
Thank you,
