>> OK class, time for your next assignment.

>> Again, the topic is "qualifying" a manufacturing process, either in house

>>
>> This is a coupon that has been proposed in the IEC specification that

>> field. As you can see from the picture, the current board is purely
>> surface mount.
>>
>> So, your assigment, in essay form, is to answer the following three
>> questions:
>>
>> 1. As a process qualification vehicle, should the vehicle be pure
>> surface mount, or mixed technology (both SMT and PTH), and why?
>>
>> 2. What would you add or subtract from the test board to make it more
>> useful to you?
>>
>> 3. Should there be two offerings of qualification vehicles, "cutting
>> edge" vs. "mainstream"? Cutting edge would incorporate fine pitch, flip
>> chips, CSPs, etc., where the mainstream board would not.
>>
>> 4. Extra Credit question: What was the greatest thing "before" sliced
>> bread?
>>
>> Doug Pauls
>> Rockwell Collins
