S-R1000’s heating zone temperature controllers have an accuracy of ±1°C and, in conjunction with a high-speed blower adjacent to each heat source for maximum convection, ensure a ΔT of ±2°C across the PCB assembly. The Series diffuser design provides low-velocity, low-turbulence air flow to prevent component shift or disturbance.
Optional thermocouples can be attached at critical locations on the PCB and connected to three built-in inputs (standard) on the oven for communication with control software for accurate, real-time temperature profiling to match any solder paste manufacturer’s specifications.
The S-R1000 is supplied as standard with an adjustable-rail, pin-type conveyor system that handles PCBs up to a maximum of 450 mm (17.7″) installed over a 570 mm (22″) stainless-steel mesh belt. The pin conveyor permits inline and double-sided processing. The mesh belt is ideal for fast changeovers.
To eliminate the possibility of jamming or dropped PCB assemblies, all components are constructed of high-quality, high-strength, stainless steel and are built to maintain dimensional tolerances at the high temperatures of lead-free processing.
Advanced automatic chain lubrication and motorized width adjustment are standard features on the pin conveyor. Automatic width adjustment of the pin conveyor, based on the parameter settings for specific reflow programs, is available as an option. For processing of larger PCBs at higher lead-free temperatures, a center support system is available to prevent board warpage.
Conveyor speed is programmable from 400-1800 mm (16″-71″) per minute to accommodate any process requirement.
While the debate over air or inert reflow atmospheres continues, as an option, offers the S-R1000 in a nitrogen-compatible configuration for manufacturers who want the flexibility for soldering in both environments.
Most experts agree that the reduction of oxygen through the introduction of an inert gas (usually N2) will allow a wider process window and provide better solder joints through reduced oxidation. The enhanced flow design of the heating chamber in the S-R1000 nitrogen compatible system lends itself to efficient heat transfer and ensures low nitrogen consumption while maintaining O2 levels between 300-1000 ppm.
Because the higher liquidus temperatures required by lead-free solders approach the limits of many SMT components and PCB assemblies, more aggressive cooling is often required to reduce peak temperature exposure times. Some recent studies also indicate that cooling rates have a significant effect on solder joint grain structure.
For these reasons, an internal water-chilled recirculating cooling system is available for the S-R1000. It allows users to alter cooling rates to meet solder paste manufacturers recommendations to a much greater degree than is possible with the exclusive use of air cooling.
Operation and control of all reflow systems is accomplished through an attractive, colorful, visual user interface that features a full-screen, virtual view of the system with display of pre-set and actual zone temperatures, system status and conveyor speed.
The Windows-based operating system and control software includes advanced functions for temperature profiling, timed automatic startup and shutdown, audible and visual alarms, and password protection.
A PC-controller with 15″ flat screen monitor, keyboard and trackball allow unlimited storage and networking capability.
All systems employ UPS battery backup to ensure removal of all product from the oven in the event of a power outage.
Axial Sequencer – The axial sequencer machine takes axial leaded through-hole components from reels and creates a tape chain of components in order of insertion for use on the axial insertion machine.
Component Lead Hole Guidelines
PCBs should be punched or drilled for component lead insertion to the following recommended hole diameters for optimum performance:
Hole Diameter = Lead Diameter + 0.48 mm (0.019 in.) ± 0.08 mm (0.003 in.)
Hole sizes:
• Less than recommended – Might result in reduced insertion reliability
• Greater than recommended – Might result in loose components in the PCB
Holes used for board error correction should be 1.0 mm (0.040 in.) ± 0.5 mm (0.020 in.). Plated holes or translucent PCBs might affect performance

“Intrinsic
availability” is the percentage of time that a machine would operate
based on downtime attributed to relevant interrupts and active repair or
recovery only.
IA = Productive time / (Productive time + Repair time) *100%
Field studies
indicate that Intrinsic Availability typically ranges from 95% to 99%. A
95% Intrinsic Availability means that 95% of the time the machine runs
without requiring operator intervention, beyond normal tasks such as
loading components. Five percent of the time requires operator
attention. 95% Intrinsic Availability translates into 24 minutes of
unexpected down time during an 8-hour full production shift. “Full
production” excludes scheduled maintenance, operators breaks, set-ups.
Intrinsic Availability does not affect board quality, but it does impact
throughput and utilization.
