1913 MKIII
What it is
General reference — not yet source-verifiedA reflow oven is thermal processing equipment used to heat assemblies according to a controlled temperature profile so solder paste can melt and then solidify into electrical and mechanical joints. Reflow ovens are commonly conveyorized systems used after paste deposition and component placement, and before downstream inspection, test, or subsequent assembly operations.
How it works
General reference — not yet source-verifiedReflow ovens move product through a sequence of heated sections and cooling sections while controlling time at temperature and heat transfer conditions. Reflow processing typically uses convection heating, and some systems can be configured for air or inert process atmospheres depending on product sensitivity and process goals.
Where it fits in the process flow
General reference — not yet source-verifiedReflow ovens are used after solder paste printing or dispensing and after component placement. Reflow ovens are used before cleaning when required, optical inspection, x ray inspection, electrical test, conformal coating, or final assembly integration.
Reflow ovens can also appear in semiconductor packaging and advanced packaging lines where solder interconnect formation is part of the assembly flow. Thermal profile control in this part of the line affects wetting behavior, voiding behavior, joint shape, and thermal exposure of components and substrates.
Why won't it start?
Documented failure modes, common issues, and field considerations.
- One source states: temperature control module NG.
- One source states: two motors removed.
- One source states: eight SSRs removed.
- One source states: the conveyor and width adjustment motors are removed.
- One source states: HC2 main control board NG.
- One source states: water cooling pipes and condenser are aging.
- One source states: the furnace in the high-temperature zone has poor sealing.
- One source states: the control circuit is severely aged and unusable, and the unit cannot be started or powered on.
