tented via definition
Tenting is a process usually delegated to dry film masks. In this process the via is completely covered to prevent cleaning solutions or flux residue from entering the plated-through hole. An issue still in debate is whether to tent one side or both sides of the via. Many users have different opinions as to which method works best in a good assembly process. With the advent and the increased use of liquid photoimageable masks, the tenting of vias has not always been possible.
