Ivas Tech put into operation the production line for manufacturing of SMT stencils

Bulgarian company Ivas Tech put into operation the production line for manufacturing of SMT stencils with precision laser cutting. The project, involving the supply, installation, testing and commissioning of new production equipment was completed with the financial support of the Operational Programme Development of competitiveness of Bulgarian economy procedure Technological modernization in small and medium enterprises.

The production line includes laser machine G 6060 for cutting of SMT stencils and vertical machining center. The machine uses precision laser source with a small beam diameter - 25 microns. Precision X, Y drive by linear motors positions the laser beam. In metal sheet - stencil precision vertical holes are formed with high-speed. Accuracy and repeatability are guaranteed by maintaining precise temperature and humidity in the workplace. The main parameters of the laser machine G 6060 are the amount of machining area of crop 600 x 600 mm, size of metal sheet 850 x 620 mm, thickness of metal sheet 0.08 - 0.6 mm; movement accuracy of 2.0 micron, management software and optimization of cutting.

Other solutions for SMT

Ivas Tech designs and manufactures cost-effective turnkey surface mount assembly systems - PLM2000 pick and place platform handing extremely high component mix, Hot-bar Soldering Machines for Luxeon Emitters, SPM100 manual stencil printer for laying on soldering paste on PCBs with the use of pre made stencil, etc. Its ambition is to become a manufacturer of full line of equipment for automated assembly of PCBs.

PLM2000 Series Pick & Place Machines

PLM2000 is the first machine designed to answer the needs of mid-volume productions CEM and OEM. A machine to face their manufacturing requirements for reliable placement, fast changeover, flexibility and minimal maintenance. In PLM200 is used maintenance free linear motors for X and Y movement, delivering outstanding performance. They distinctly boost placement reliability and the machines life and cut the maintenance and support expenses.

Great placement accuracy thanks to integrated into our new light-weight placement head precision digital CMOS camera for component and Fiducial mark recognition. The high speed on-the-fly vision processing system enables quick and precise placement of 0201 up to 20x20mm components

Original red lighting facilitates the camera to recognize Fiducial marks and shapes on materials with a variety of backgrounds. The connection between the machine and PC is controlled via isolated CAN interface also recognized for being highly reliable and very fast. To be able to face the demands of high-mix assembly, PLM2000 can be equipped with 210 positions of 8mm tape feeders. Also it can be equipped with tray feeders and vibe/stick feeder. The feeders are servo motor driven with build-in electrical motors. Depending on the component’s size / weight six different nozzle sizes are available.

Additional increase in throughoutput and flexibility can be achieved with the optional modules. In order to ease the production, IVAS Tech offers the following smart features:

• Laser positioning devise sensor for automated set Z axis

• Dispensing system for solder paste and / or glue

• Supplementary upward looking camera for ICs greater up to 40x40mm

• Automatic Fiducial recognition

• Special feeders for components up to 15mm tall

• SMEMA compatible conveyor module

• Process Statistic Management - provides the management staff with access to information regarding production run / saturated PCBs, number and description of the assembled components, working and stand by period etc.

PLM2000 is the ideal solution for contract manufacturers and OEMs with small to large board sizes and variety of production volumes.

Hot-bar Soldering Machines for Luxeon Emitters

HBSM - (Hot bar soldering machine) is a highly efficient and cost effective system for automated consecutively assembly and soldering of Luxeon type diodes. Luxeon is an energy efficient and ultra compact light source. They combine the lifetime and reliability advantages of light emitting diodes with the brightness of conventional lighting. Due to their relatively low recommended storage temperature the standard reflow soldering process for array assembly can not be applied to them. For this reason the Luxeon’s manufacturers recommend a hot-bar soldering method. This is a process that transfers the heat only to the pins of the LED and avoids overheating the emitter and lens of the device.

HBSM is a highly efficient and cost effective system for automated consecutively assembly and soldering of Luxeon type diodes. Our class of production equipment reflects the industrial developments and quality requirements of high-end equipment manufacturers at a fraction of the capital investment. We use maintenance free Linear motors for X and Y axes movement, proven to be the best in the industry. Implemented into the pick and place head are the glue and flux dispensers, anon-the-fly digital CMOS camera and hot bar tips. In the HBSM soldering temperature, speed of movement and pressure of the soldering tips are adjustable with fine precision. The tips generate a high energy density heat in a short timeframe, preventing opens and shorts. A specifically designed nozzle ensures damage free pick - up of the Luxeon LEDs and holds the component firmly in precisely during the placement and soldering process. Two Archimedean screw dispensers attached to the head deliver precisely controlled amounts of adhesive and flux. In spite of its small footprint, the HBSM will provide you with a big performance / price ratio for Luxeon LED automated placement and soldering; allowing you to implement an accurate repeatable cost effective process.

Full convection reflow oven BTO 62

The BTO has been developed for reflow soldering of hybrid boards, SMT board and curing glue or thick film pastes. The machine is suited for small and medium series of assembly work.

• Low or mid production requirement in the range of 300-600pcs/8hours (A 300x300 PCB is taken as reference).

• Lead-free requirement.

• It is possible to bake some no-PCB products if the requirements for a uniform temperature are fulfilled.

• Tight space and tight budget.

The reflow oven uses a micro-processor control over the temperature, which enables the storage of 16 groups of temperature parameters and adds 2 additional ports for temperature testing.

The CE certificated blower is specially design for lead-fre reflow oven. It runs stable and with lower noise. Upper zone hood and electrical box cover can be opened easily. This makes the oven convenient for cleaning and maintenance. The inner tunnel of the oven is made of stainless steel which is easy to clean. All upper zones are with forced air convection which provides great temperature accuracy and uniform. The conveyer belt is made from stainless steel. Optional aluminum cabinet for stand.
