What do you mean by "substrate?" Is it: * Semiconductor die * BT circuit board interposer Is the BGA package: * Encapsulated * Mounted on a circuit board

I would like to ask a few things about die crack. 1. I would like to know what could possibly be the root cause of die crack in die preparation? (Saw machine? Pick and Place machine?) 2. May I know how could I solve the problem? Thank you very muc

There are a few questions I have before we can answer this: 1. How are the die presented to the pick and place machine? (Tape, waffle Pak, tray) 2. What are the dimensions of the die (LxWxH)? 3. Are they bumped die? 4. What is the material of the

Okay so you are picking from a Wafer Frame and it is a UV cured tape. Who's die sorting machine are you using? You mention the ejector needles, but have you checked them? What size are the die and how thick are they? Have you checked the UV cure, i

It's OK to have the daisychain done in the interposer rather than the die (and a lot cheaper) but in thermal cycling the parts MUST have representative die. That's where a large part of the CTE mismatch comes from to cause fatigue damage. Thermal c

We have an old Conceptronic oven (Discovery Mark IV) which we use in the glue process. The video monitor just died. This is a 11 year old oven with a Goldstar model 1420 PLUS monitor. There are no specs in the manual and Conceptronic is not much help

Does anyone have the Falcon vision board that comes in the Contact 3AV? It controls the cameras and monitor. I am pretty sure mine died because the monitor is all garbled. I think it is the same board that comes in all the 3 series models..... Thank
