Hi Uzbek, this is Alice from Neoden. Do you consider a new PNP machine? We are a professional manufacturer and Neoden7 seems to meet your need. We also could provide a complete SMT solution with competitive price, reflow oven, solder printer, etc.

As a manufacturer, I prefer plated nickel gold, electroless nickel immersion gold, immersion silver and palladium. These surface finishes are the best options to replace leaded surface finishes. These surface finishes can withstand higher temperature

I think it might be the best choice for OEMs that only run one finish and practice JIT. (taking cost into account) For everyone else I think they will eventually run into trying to use them too long after they have been opened. But when you can run b

flux my leave a white residues even after cleaning, when we want to select a flux for our Ersa Ecoslect we tryed a varity of fluxes (including the IF2005C) and we decide to use the Cobar 390-RX-HT because he gaved us the best results in soldering and

hi Team, observed excess solder after assembly jumper with manual solder method. I already try to duplicate the phenomenon with adding more solder tin/wire,adding more time for solder but not found same condition I have attached the image for the

Hi Experts, If SMT Type DDR DIMM Socket , PTH Pin size:2.5mm , PCB hole 2.45mm, Could this design can use placement machine to put DIMM on PCB? How to overcome the interference between PTH pin and PCB hole? Thank you Best regards James

When I hear "pinholes" in solder connections, I think of two sources, depending on the situation, which can be either: + Entrapped air and process chemicals develop during reflow soldering to cause the pinholes in and around the intermetallic layer

You proved that the standard solderability test of components may be effective for assessing aged components. Curious Minds Can you get the authorization to use a more aggressive flux? Will that flux solve the problem? What's it going to cost to qu

I'm not conversant in the topic, but I know suppliers to the government are concerned as you are. I have attended sessions on the topic at technical conferences. The topic that you want to search for is long-term storage protocols for electronic comp

We had a customer who used XRF to determine the thickness of the "tinned" layer of components - sort of what is briefly mentioned in Bob Klenke's SMTA paper - http://www.circuitinsight.com/pdf/Solderability_Testing_Protocols_Component_Re-Tinning_Me
