Q1: How many mils the gap between the terminal and pad? A1: It depends on properties of the glue and z-force when the component is placed by the assembler. Q2: Your practice is for technology SMT-4? A2: We don't understand SMT4. We know that very sm

Assuming the following: L=Process Length of the oven t=Desired profile time in mins(depends on the paste/glue used) l=PCB length l1=gap between consecutive PCBs Then the total no. of PCBs per hour is" (L*60/t)/(l+l1) Vinit
