Hi I completely agree with you. Also, the Dry Solder paste can be used in wireless repair operations such as the repair of smart phones, tablets, laptops and other handheld devices. The lead-free solder paste can be squeegeed through the apertures of

After reading the variety of responses, I feel moved to ask if you're you talking about what are occasionally referred to as solder beads (mid-chip solder balls, attached to the waste line of your chip caps and resistors) or the solder balls that ten

It has been our experience that the problem you have discribed was not solder process related. We had two such instances in the past and both were component related. The first case involved a PLCC28 that failed test. Reflowing the solder seemed to co

| Has anyone had any experience or data using vibration during the reflow process. | We introduced a vibration device attached to the fixed rail on a Vitronics reflow oven. The reason was to prevent skewing on large PLCC devices. The process worked v
