Lead Free solder Technology  Alternative PCB finishes Engineering support always AOI test PCB Assembly is a process of mounting and assembling of Components on the PCB. It not only requires knowledge of PCB components and Assembly processes, but also of printed circuit board design, PCB fabrication and a strong understanding of the final product. Circuit board assembly is just one piece of the puzzle to delivering the perfect product. MKTPCB is a one-stop solution fo r all circuit board services so we are often entrenched with the PCB production process from design to assembly. Through our strong network of well-proven circuit assembly and manufacturing partners, we can provide the most advanced and nearly limitless capabilities for your prototype or production PCB application. Moreover, we can help you to reduce the trouble that comes from the procurement process and dealing with multiple component and part vendors. Our experts will find the best parts for your final product ensuring good stock, best prices and fresh produce. We offer the following PCB assembly services: Quick-turn prototype assembly Turn-key assembly Partial turn-key assembly Consignment assembly RoHS compliant lead-free assembly Non-RoHS assembly Conformal coating Final box-build and packaging Surface Mount Technology/Part �?SMT Assembly�?
