Use IPC-4552 for your ENIG thickness. Typically, ENIG has nickel deposit with medium [7-9 percent by weight] phosphorus content. That's what fabs do on rigid boards. On a flex with medium-P and IPC-4552 specified ENIG, you could see brittleness and

Hi, We are considering adding on to our SMT line. Our current line is CP65, IP3 and we would like better placement on our 0402's and 0201's. We were looking at the NXT, we would need larger pcb table to match our other machines. We probably only nee

Yes, we have the Agilis stick feeder and it is a definite improvement on the vibe. It usually comes with a set of starter 'tubeforks', but i bought another starter set after a while since the individual tubeforks are relatively expenisive. Always g

Hi, follow up, Thanks to everyone that responded. We finished the build, the sun burst thru the clouds and the birds sang. Well that was a slight exageration. Sorry for lack of detail on the original post, I was frazzled. Since the 0201's were p

Quick Question! We have an assembly that we're building for a customer that will have to be soldered via a Lead-Free Wave Solder. We do not currently have a Lead-Free Wave Solder in house. Does anyone know of a company that may be able to provide thi

Every paper I've seen published shows that BGA voids either have no effect or actually give a slight improvement. The one exception are voids with a root cause in bad incoming boards, such as champagne voiding where nearly the entire interface is go

This is a snip from an ealier post here on SMTnet. Generally, solder pastes are comprised of: 90% solder powder, 5% flux, 4% solvents, and 1% activators [by weight]. Where: * Solder powder, when reflowed, is a metal bonding agent that mechanically

Confirm the source of the issue. Run a coalescence test on both lots of paste. A simple coalescence test can quickly determine the condition of solder paste after prolonged use. Simply print a small disk [around 4-5mm diameter and 0.2mm thick - a bu

I like to cook my lunch thru the ovens on 2nd shift. just heat it up more than anything else - but it works. I think if you just get the right heat into the food it will kill the bacteria. Now I prefer convection over IR. Call me old fasioned, bu
