We are manufacturing an NPI board for a Customer and they want us to wash the board using a Saponifier wash. However, one of the SMT parts cannot be placed through a wash process. Has anyone ever had to encapsulate a component to prevent water da

Have you considered mounting this component after the assembly has been washed. Then, mounting the component and cleaning its solder joints individually. Alternatively, have you considered using alternative cleaning solutions to a saponifier (and a

I don'treally think anyone can give on answer on this one because we don't know what size the any thing is, or how many operators will be running, or where your parts are and the how you set up, if you need a staging area. There are just to maney wha

Hi Mike, We mainly use chillers for the operators - we build a lot of thick & palletised boards that retain the heat. Having a chiller means we can pick the board up earlier after the oven & it's cooler. With leadfree you will have higher temperat

Hi, I am an Engineering student doing some research on the component/nozzle interface on SMT Pick and Place machines. Could anyone tell me the force at which the nozzle hits the component as it is picked from the feeder or the placement force on a
