Cameron, I am burying the thermocouple in high temp solder on the solder pad of the area I want to profile.

Hadco offers a technology of building in a "buried" capacitance layer (& other embedded passives) in organic PWBs (FR4 for example). see http://www.hadco.com/prod03.htm and a design manual is posted here: http://www.hadco.com/pdfs/bcguide.pdf I am c

Could anyone send me equations to calculate controlled impedance of traces on circuit boards. I am most interested in the buried traces in multi layer boards. Thanks, David - piengr@verinet.com

When we see dewetted solder on pads, we sprint to get sections done, in order to determine if over-exuberant pumice scrubbing by the fabricator has buried material in the copper.

since I'm new to the subject of printed circuits, I wonder wether some one can explain some fundamental subjects to me: 1. What is FR4? 2. What is SMT? 3. The technology of multi layer printed circuits? 4. What is "Blind and buried vias"? 5. What is

Chris: Thanks. SMTnet has a "Library." Buried deep within it is a listing of terms. The following is from that listing: Shadowing. When a component blocks the heat or solder wave flow from certain areas of the printed circuit board, resulting in

Bert- There's alot of forums dealing with SMT and Fuji in particular but you'd have to be able to read Chinese. In China... being fairly new to this there are many help forums around designed to assist folks to get up to speed as quickly as possible

This process is going to make conventional rework, and most mods and ECOs impossible. You might be able to make some changes by patching a component across the exposed pads, but most of the circuitry will be buried. You could, of course, make speci

Let�s say I want to increase the shear strength of a solder joint. Does a lot of solder around a joint create more strength? Why not just absolutely bury the component lead in solder. My initial thought is that it doesn�t increase strength, but I don
