What is Parallel Seam Sealing

Parallel seam sealing is a method of hermetically sealing packages with lids that contains electronic components.
Using the principle of resistance welding, brazing materials such as nickel and gold-tin are melted and sealed by resistance heating.
Compared to other joining methods, this method has less thermal effect on the internal elements and higher joining strength.

Features of Parallel Seam Sealer

The main applications of Parallel Seam Sealer are quartz crystals used in communication equipment, acceleration sensors, and MEMS.

Nihon Avionics' Parallel Seam Seals have the top market share in the field of sealing crystal oscillators. The lineup is ranging from fully automated types for use in mass production to small-lot production and R&D applications.

Application examples

  • Crystal oscillators, SAW devices, vibration sensors such as acceleration sensors and angular velocity sensors
  • Optical devices such as laser devices, image sensors, and mirror sensors
  • All-solid state batteries, medical devices, etc.

Parallel Seam Sealing Products

Parallel Seam Sealer must seal packages in the vacuum or nitrogen atmosphere, depending on the device to be sealed. Various models are available, from high-speed types with a machine tact time of 0.8 seconds to the type capable of sealing packages of 150 mm in size.
