Hi, this is not really a technical solution, just a feedback. we too have a model series using the same WS paste type. it gives a dull solder joint with white residue that can be marginally removed after post-DI water rinse (ie. not 100% removed).

I have a couple of questions for you, and a couple of answers. 1. Which model ? (100, IIc, IVc, QSV, QSP ) 2. In reference to how the machine stacks up with Fuji and Panasonic. They have never stacked up. Those families of machines have historicall

Hello all, I am having soldering issues with an Everlight component it is a TM4201/TR2 (Right angle IRDA with a 1mm pitch). The problem I have is that after reflow the solder joints look perfect, but during test we are losing 7 micro amps as soon as

Boy, I step out for a bit and everybody picks on me (just joking). I believe I may have been off base a bit. Checking every bit of your stencil design is very good - I do that too. I calculate LXWXH and reduce or over print where needed, depending

I can not find a F4G in Fuji�s equipment list. Siemens has a F4 ( flexible fine pitch machine ) and also a GII ( glue dispensing machine ), which both would make sense to add to your equipment list. Machines are �connected� together with their conve

We are a company that designs a product but gets the PCB fabricated and the surface mount assembly done out of house. The product then comes in house and we test it, do some final assembly on it, and ship it. We recently had a prototype run of PCB'

I'm not talking about buying components. I want to know how would you go about setting up an SMT line from scratch. Or, maybe more specifically, how do I convince management, with data to back up all my arguments, that this is not a good idea. That

Management is talking about the ability to do all our assembly in house. I would assume that realistically that we would eventually limit it to a few key products, but we are a high mix, relatively low volume company with volumes going up. We have
