SMT (Surface Mount Technology) – Liberty Engineering Inc. specializes in demanding surface mount technology boards, down to 0201 size components, including BGA (ball grid array), LGA (land grid array) and other odd size parts. X-ray inspection equipment is utilized for inspection of BGA and LGA parts. We work closely with our customers’ engineers to meet their demanding specifications. We build with tin/lead solder or RoHS lead-free solder per our customer’s requirements. [add picture of X-ray, surface mount part board]

Through-hole Technology – Our company specializes in through-hole technology boards, including legacy technologies and challenging heavy copper boards. Soldering capabilities include tin/lead solder and RoHS lead-free solder. Soldering technologies used include wave solder, selective solder, or hand soldering.
