Have at least five thermocouples been used at various points on the board to establish the Thermal Profile? Note* Is there evidence that a once off comparison study been conducted for a loaded versus an unloaded oven? derived from the Paste & Component manufacturer’s recommendations but controlled to a narrower window?ĭoes the product Temperature Profile fall within the Engineering based specification for the process window?ĭoes the product Temperature Profile fall within the Engineering based specification for glass transition temperature requirements?Ĭan any excursions outside of the process window be justified and supported with hard evidence and logical analysis?ĭoes the product Temperature Profile meet the reflow requirements for the SMT components according to the component manufactures?Īre the boards used to establish the initial Thermal Profile kept as engineering samples? Is there available an Engineering based specification to detail the acceptable process window for Temperature Profiles? Were the Temperature Set Points and Conveyor Speed logged for that Thermal Profile when it was conducted?ĭo the Temperature Set Points & Conveyor Speed written on the Thermal Profile correspond to the current Program settings? Is the Temperature Profile assessable and readily available to operators / technicians as and when required? Is there available a Temperature Profile for the product currently being built? Is access to the machine program password protected with restricted access?ĭo program changes to critical parameters during machine control remain unsaved unless approved by a technician/engineer? Is the machine Program Name traceable to the PWB and PCBA part number? Is the machine Program Name revision controlled to show traceability of program changes? Is the Reflow technology in use suitable for the product being built? Must be full forced Convection with sufficient zone count.Īre air flow controllers or a centralized control system used to balance exhaust flow rates for each individual exhaust drop?Īre exhaust flow rate ranges specified and monitored on a regular basis to insure compliance? Is the machine Program Name specified on the Work Instruction or set-up sheets? When center rail support is required, do Work instructions indicate this requirement and is the location specified? Is the conveyor speed set point specified on the Work Instruction and is it the same as that specified in the program?Īre the temperature set points specified on the Work Instruction and are they the same as those specified in the program?ĭo Work instructions indicate if pallets or other tooling are required? Only 1400 mm (55") long, heat length 1000mm (39")īench-top models, small space, suitable for low-middle batch production.Is there a revision controlled Operator Work Instruction which contains set-up information for the specific product being reflowed? (Score 0 if any unsigned/undated handwritten instructions or any handwritten instructions more than 48 hrs old)Īre Work Instructions readily available to the operator and are they followed at Reflow? PID temperature control from room temperature to 400☌ (750☏)ģ00 mm (12") wide stainless steel mesh conveyor with speed variable from 200-1800mm (7.8-70.8") Three independently controlled heat zones Key to the reflow oven precision and reliability is an innovative and compact design for efficient heat transfer and maximum thermal stability. With a 12" mesh belt conveyor, three independently controlled heat zones, the affordably-priced can be used to produce accurate, in-line, time/temperature profiles to meet your specific processing requirements. They are designed to the highest standards and cost performance. Reflow oven for small batch production runs with extremely uniform temperature profiling across the board for enhanced process control.Three (3) heating zones Reflow Soldering Oven is a multi-function oven, suitable for a wide range of curing, drying and heat-treating applications. SMD reflow ovens are available for both conventional and lead-free solder. Product name:Table Top Reflow Oven (Conveyor)Item:Details:
