We are going to be placing some 15 mil quad flat packs on a pcb assy to be used in an automotive like eviornment (off road vehicle type of vibration is possible) and are wondering if there are any special processing steps that we whould take to enhance field reliability. Our customer complains that previously tested engineering samples that they made had some problems with the fine pitch. We've not encountered this type of issue befor. We and our customer would appreciate any input you could give us. Thank you in advance for your consideration. Leo Reynolds
