Vibration absorption tubing and a manufacturing method thereof. The manufacturing method includes: a solder placement step including: placing solder at solder placement portions in an inner cavity of an adaptor; a pipe fitting step including: fitting a corrugated pipe and the adaptor respectively to adaptor matching portions at corresponding sides of the adaptor, to communicate an adaptor inner cavity with an inner cavity of the corrugated pipe and inner cavities of external connection tubing; and fixing or limiting positions of the corrugated pipe, the adaptor, and the external connection tubing to obtain a tubing assembly; and a component brazing step including: performing furnace brazing on the tubing assembly of the external connection tubing to obtain a main vibration absorption tubing. The vibration absorption tubing has favorable brazing consistency, enhancing connection reliability of components.

A method of joining electronic components to an electronic substrate in an apparatus includes: (1) transporting electronic substrates through a chamber housing including a tunnel extending through multiple processing zones; (2) detecting temperatures of the electronic substrates passing proximate to a heat detection system including at least one temperature sensor coupled to the chamber housing; (3) receiving temperature data from the heat detection system with a controller coupled to the multiple processing zones, the conveyor, and the heat detection system; (4) determining, by the controller, with reference to the detected temperatures of the electronic substrates, an adjustment to at least one of (a) a heat setting of a heating element within the chamber housing, (b) a speed of the conveyor, and (c) an operational speed of a blower within the chamber housing; and (5) performing the determined adjustment.

The disclosure relates to a brazing method for joining substrates, in particular where one of the substrates is difficult to wet with molten braze material. The method includes formation of a porous metal layer on a first substrate to assist wetting of the first substrate with a molten braze metal, which in turn permits joining of the first substrate with a second substrate via a braze metal later in an assembled brazed joint. Ceramic substrates can be particularly difficult to wet with molten braze metals, and the disclosed method can be used to join a ceramic substrate to another substrate. The brazed joint can be incorporated into a solid-oxide fuel cell, for example as a stack component thereof, in particular when the first substrate is a ceramic substrate and the joined substrate is a metallic substrate.
