I have used conductive adhesives for some time now on thickfilm. Does anyone know of a really good conductive adhesive to attach flip chips to flex circuits? I would like to stencil print the adhesive to the substrate and then place the flips chi

this document http://www.latticesemi.com/view_document?document_id=671 may be good start point but note that how to escape from the BGA is not big deal, how to route your filtering capcitors, grounding, impedance control lof you high speed signals ar

Hi, i have a confusion to read the dimension of BGA package from the datasheet. I have attached the datasheet below. Is this diameter of the ball 0.30mm or 0.15mm. I'm confused about the values given in the box. Whats meant by M, S, A and B. Please g

I'm planning to design the pcb of my project. The controller used is having 136 pins and the package is P-LFBGA. So i think i need to design a 6 layer board for better performance. I haven't designed a multi layer board before. So what are things tak

if the BGA has leaded balls use leaded paste if the BGA has lead free balls use lead free paste and set your oven profile to match the paste

I seemed to have learned that on the bga chip that the soider is the soider balls on the chip. If this is true how do you get the chip to not move on the board when being inspected bdfore you soider it. and even in the transport of the board to the o
