The consequences of poor heel formation in solder connections include: * Lower solder joint strength * Possible intermittent short circuits * Reduced first-pass yields * Increased inspection cost * Increased rework cost * Likely field failures * Likely damage to your company's brand & image * Likely educed sales and profits
