I didn't wade thru all of the info you presented above, but your comment about ampacity of printed circuit boards brought to mind a copy of an article I keep in my files. Luckily I photocopied the whole page from the magazine and can actually tell y

We are looking into using Scored PWB's on a new high volume design. We've used Tab Routed PWB's exclusively in the past. I understand that Scored PWB's are more efficient to produce and depanelize. Question: What are the industry standards for cr

When carry out the contamination test,do we measure for Chlorides on water soluble and No-clean fluxes? 1) What is the equivalent factor for machines developed to test the board cleanliness, Omega-meter vs Ionograph vs Zero-ion. 2) What values do we

Just so that you know, the 5DX does laminography. Like the word lamination, laminography takes a series of short focal length xrays, each a little deeper than the previous. Microlaminography allows layer by layer information to be measured in 'slic

A flexible array support system is superior in the following categories discussed in the 'tooling classes' thread. -High Flexibility -Effective on a variety of products -Low operator intervention -Conforms to PCB, so it is both accurate and repeatab

I am also interested in one of Anthony's questions....How is this different from other "similar" products. After having some experience with similar technology, I ask.... 1. How does your initial set-up address the fact that you are conforming to a

Research was done into the deflection of a totally unsupported (topside) PCB of 0.050" thickness. A dial indicator was placed on the surface and the tooling was set. The deflection ranged from 0.005" to 0.007". This is minor when you consider th

Please excuse me if this question has already been answered, but what separates this type of tooling from say the Transition Automation "Board Lok" tooling (which I tried out and hated) or the DEK FormFlex. Since I am based in the UK I have a chance

The reason we're putting the epoxy in at the last process is two fold really. 1. as you suggest putting the componnd down prior to placement is going to cause issues around the placement of the device. But more importantly 2. the material speced by

Generally speaking with most electronic grade epoxies: 1. Cure time is a function of temperature. 2. Polymer bonds begin to quickly break down above certain temperatures (product specific). I believe aprox 170-180C. The strength of the bond de
