140℃ heat-resistant magnetic sensor for battery inspection High density bonding

A 140℃ heat-resistant magnetic sensor is high-density bonded to realize a two-dimensional magnetic sensor array.

specification

Special Stipulations MONSTER PAC® 120°C low temperature bonding

Conventional method 1

Mounting by wire bonding method   ▼ Cannot be implemented in close proximity to the wire direction As a magnetic sensor, it becomes a one-dimensional sensor   ▼ The sensor side or the inspected side (battery) need to move and scan   ▼ Inefficiency

Conventional method 2

Flip chip bonding by solder
  ▼
Heat-resistant temperature of magnetic sensor chip is 140℃
Solder reflow temperature is 260℃
  ▼
Sensor characteristics deteriorate
  ▼
Not implementable

Conventional method 2

MONSTER PAC® Method

MONSTER PAC®️ Method

Low-temperature and low-load MONSTER PAC®️ 120℃ bonding
  ▼
Because there is no wire, it can be implemented in two dimensions
Because the bonding temperature is 120℃, no deterioration of the magnetic sensor chip
  ▼
Full bulk inspection is possible without the characteristic deterioration
  ▼
High efficiency
