Dimension of D1 and E1 do not include mold protrusion. Allowable protrusion is 0.25mm per side. Dimension D1 and E1 are maximum plastic body size dimensions including mold mismatch. -C- SEATING PLANE SIDE VIEW 2. Dimension b does not include dambar protrusion. Allowable dambar protrusion shall not cause the lead width to exceed the maximum b dimension by more than 0.08mm. Dambar cannot be located on the lower radius or the foot. Minimum space between protrusion and an adjacent lead is 0.07mm for 0.4mm and 0.5mm pitch packages. 3. All dimensions of the 128 lead package were based on the 120 lead package since they are not mentioned in JEDEC spec MS-026.
