The dielectic absorption characteristic of printed circuit board materials is usually not listed on the manufacturers spec. sheets. Can anyone point me in a direction to help determine which laminate materials might exhibit better dielectric absorpt

Phuc, One word of advice... Be sure to investigate your rework capabilities if you are going to use ceramic components. It gets tricky and expensive.

Phuc, John is correct about the physical dimensions of the part and the problems surrounding them. This does not mean they are a problem for SMT. They can be placed with little trouble by the machines if you can spend the money on the right equipme

I am researching a process call Collumn Grid Array for the BGA. Please email me if you have some knowledge about this process. The problem is ceramic BGA has different thermal coefficient with PCB (FR-4) material, and in extreme temperature (-40 C-

The CCGA package is difficult to handle and automate in the assembly process. The leads can be fragile, and vision recognition of the package and leads is difficult. Special lighting and/or a special vision algorithm will probably be needed if you wa

The CCGA is like a BGA except that the columns are more square looking and there are many more of them. They are made of lead so they are very fragile. They are very expensive. There is a special cleaning process they have to go through once it has b
