Hirox Digital Microscope System: MX-BGAZ II

This BGA lens allows ball joints to be observed non-destructively. Also, a 3D optical rotary ring enables 3D observation. This lens incorporates special hardware, such as a prism tip with lighting and a cushion mechanism, to ensure comfortable observation.

Furthermore, observation of the BGA exterior in detail helps specify various problems, such as overheating, oxidation, air foam formation, and their causes. The [MX-BGAZ II] allows inspection of the BGA ball's upper and lower joints by changing the observation angle through the optical rotary ring. This information is useful in reviewing the temperature profiles.

Exterior analysis clearly identifies defects

Hirox MX-BGAZ II Preheating Not Melt

Because preheating is too long, flux deteriorates and the ball is oxidized and does not melt.

Hirox MX-BGAZ II Detachment

Detachment caused by outer pres- sures, detachment from the land be- cause of unfavorable junctions.

Hirox MX-BGAZ II Heat Quality

The heat quantity from the upper heater is large, parts are warped, balls are extended and the light hala- tion is out of alignment, coming to the lower part of the ball.

Hirox MX-BGAZ II Preheating Joined

Because preheating is too long, flux deteriorates and the ball and the solder are not joined into one.

Hirox MX-BGAZ II Light Halation

Hirox MX-BGAZ II Light Halation Judgment

When light halation is observed at the center of the ball, it indicates that heat balance is favorable and the ball is round-shaped. BGA mounting uses light halation as one standard of judgment.

Easy and Accurate exterior observation

Exterior observation allows for defect analysis of BGA mounting substrates and the creation of environments for preventing defects. It concentrates HIROX’s unique knowledge and technologies for observing BGAs from various angles in an easy manner. The use of this lens allows anybody to become a high-level engineer and to make precise exterior observations.

Optical rotary Ring

Rotating the ring changes observation angles. Without moving the lens and substrates, it enables detailed analysis of upper and lower joint parts of the BGA ball.

Focus Ring

Rotating the ring facilitates focusing on the BGA.

Mode Switch Ring

Rotating the ring switches the observation range without changing the distance from the lens to BGA and allows confirmation of parts warpage and uplift on mounting substrates.

Illumination-attached prism tip

A 45° prism mirror helps view the BGA ball from the side. This prism tip serves the role of a light guide, and enables bright, high-resolution observation even on a concentrated substrate.
