If you are doing double sided smt you need to look at a pin chain conveyor on your oven, not just a mesh belt. Regarding vapour phase I'm not an expert, but I've not seen one run with Nitrogen - as I understand it the vapour creates an inert atmosph

Although if you do many double sided boards you will want to avoid having to constantly fit boards with unreflowed components on into jigs, as there is plently of opportunity for defects. It's fine on the odd board, but doing it a lot is something t

They used to be sold under the Samsung brand in our region, the old CP40's & 45's were good machines. I know people who ran them hard for many years with no issues. Haven't had as much experience with the SM*** machines, but people I rate like the

Regarding the oven, do it. It's $250 USD and it will teach you so much if you have scrap boards and an oven profiler to play with. Your paste supplier may be able to help you here if you don't. Right now you are in a knowledge gathering learning p

Thanks Rob, I bought it. Agreed its a good way to get my feet wet. By my math, it should do 1 10" board per minute. Too fast for even my dream production setup. So I may become a huge fan if it works. Not considering Nitrogen unless it doesnt wo

There is no local support for Juki or Samsung in Chicago. If I pay $5000 Samsung will be able to monitor everything remotely. I am still unsure of the life of a pick and place machine. I have seen some Universals get to 50,000. Not sure about Ju

I have 2 - one in an old line with 2 x 750's that we are waiting to swap out, and one spare. They are glacially slow, they are no longer supported (although we have good second user spares form China). A 750 is much quicker. If you know for a fac

The only real local support I am finding is for universal instruments. I have remote support. What machines in the under $10k with feeders category for learning on do you recommend? Most likely leaning to upgrade to a used samsung machine in a ye

one caveat to be aware of is the power requirements of many machines. Most 'industrial level' pick and place machines, as well as reflow ovens will require 3 phase power. it sounds like you are trying to set this up in an office type environment. Do

Thanks. A few thousand used or new? My machines didnt run that much so I am trying to save on this. Seller sold his conveyor when he did his liquidation sale. Is it required between a screen printer and a SMT machine or can they be put into one an
