We use a MIRTEC high res bench top system and are real happy with the performace. We have used it for both pre-reflow Mainly checking parts and part numbers) and post reflow for everything including solder joints. Easy to program and as you do more

Bismuth Solder alloys * Fatigue life is reduced when soldered to hot air solder leveled (HASL) boards. * Lead from Hot Air Leveling (HAL) coatings can diffuse through the grain boundaries of alloy. * Lead is bismuth alloys can form a eutectic composi
