The only different between these two technologies are: 1) the male pin will be make to fit the female hole on the PCB fabrication. 2) In order to achieve join structure, press-fit will use pressure to put the male pin into the female hole on. For many years the design of stencil apertures has been based around the original IPC7525 specification1 which recommended that aperture area ratios should be greater than 0.66 for acceptable stencil printing (to achieve in excess of 70-75% transfer efficiency). The ‘historical’ transfer efficiency curve in Figure 2 is

Stencil Design RulesDesign Rules of SMT Stencils. The size and shape of SMT stencil apertures determine the volume, uniformity, and definition of the material deposited onto substrates. Aperture sizes can be determined using measures such as area ratio. Each Stencil manufacturing technique considers its merits when designing apertures following these rules. STENCIL DESIGN FOR FINE PITCH COMPONENTS Transfer efficiency ratio between the volume of the deposited paste and the volume of the aperture It is determined by three main factors from the viewpoint of the stencil itself Manufacturing technology of the stencil Aspect ratio AS length of aperture s shorter side divided by the

Two types of land patterns are used for surface-mount devices: 1) solder mask-defined (SMD) pads have solder mask openings that are smaller than metal pads, and 2) nonsolder mask-defined (NSMD) pads have solder mask openings that are larger than the metal pads.
