What kind of cleaning method you recommend for PCB - double side SMD (fine pitch and BGA components) and THT elements (PCB are for microwave application!!). Process technology no-clean.We have to remove grease-fingerprints, dust etc. It is low volume

Correct preheating of the assembly is critical. Check with your flux manufacturer regarding the recommended topside pcb temperature as it enters the first wave. It is important that this temperature be achieved without burning the flux on the bottom

Hi! Just joined the circuit. Hot Bar soldering is very reliable provided the Flexible Printed Circuit (FPC) and Rigid PCB design support this technique. Some of the critical aspects that need to be considered include Stencil apperture design for sold

Does anybody out there have experience building electronics assemblies with DCA (Direct Chip Attach - bare die onto PCB) and wire bonding? - What Die Bonder/Dispensing Machines are recommended? - What brand conductive epoxy were used to attach die?
