Our assembly floor runs automated SMT placement lines alongside selective and wave soldering for through-hole components, so mixed-technology boards run through a single production flow instead of being split across vendors. Placement accuracy holds tight enough for 01005 passives at one end of the range and large BGA, QFN, and CSP packages at 0.3 mm pitch at the other.
Both lead-free and leaded process lines are qualified, and stencil design and paste-print parameters are engineered per board rather than reused from a generic template — a meaningful source of first-pass yield problems we see when programs move from another vendor.
