Boundary scan engineering service
Jaltek Systems boundary scan engineering service can begin with a design-for-test analysis aimed at raising a product's boundary scan compatibility at the early stages of the design process.
Offered as either a stand-alone package or part of a full manufacturing contract, Jaltek Systems boundary scan engineering service can begin with a design-for-test analysis aimed at raising a product's boundary scan compatibility at the early stages of the design process With the introduction of Jaltek Systems full boundary scan test engineering service, customers can benefit from reduced engineering costs, faster time-to-market and improved confidence in product performance and reliability

Laser reduces flat part cutting times by up to 50%
USA-based subcontract sheet metal working company reported that its recently acquired 4kW laser system is literally cutting days off delivery lead-times.
Jaltek Systems Director of Technology, Leon Dixon, explained: "Although traditional Manufacturing Defect Analysis (MDA) techniques, such as Automatic Optical Inspection (AOI) and flying probe are excellent tools for inspecting components and open lead-frame devices, the year-on-year increase, of some 25 per cent, in the use of full Ball Grid Array (BGA) parts is steadily reducing test access." "With a technical capability ranging from trapping shorts/opens to programming FPGAs, boundary scan straddles the MDA/functional test processes and complements traditional inspection methods." Jaltek Systems chosen boundary scan tool is Asset Intertech's ScanWorks, offering capabilities including interconnect (shorts/opens access and reporting), flash devices (write, read and verify), FPGA, CPLD and memory (write, read and verify).
Regarding memory test, bespoke scripts can be written for esoteric configured memory which is conventionally accessed through the bus.
Offered as either a stand-alone package or part of a full manufacturing contract, Jaltek Systems boundary scan engineering service can begin with a design-for-test analysis aimed at raising a product's boundary scan compatibility at the early stages of the design process.
Using its manufacturing, test and supply-chain experience, Jaltek Systems can guide engineers towards readily available components with proven manufacturing and boundary scan compatibility.
For companies with offshore outsourcing policies, Jaltek Systems boundary scan service offers a scalable capability during test integration, by providing engineering documentation and data packages for the manufacturing facilities.
Likewise, Jaltek is applying its boundary scan experience to re-engineering legacy products, some up to six-years old.
In the past, some manufacturers have started boundary scan integration but abandoned the process, leaving unconnected nets across the product.
Such legacy products can now be assessed and re-engineered for boundary scan compliance.
Leon Dixon continued: "For new and legacy products alike, reliable test access is vital".
"Many products already feature dedicated boundary scan access ports in the form of IDC headers".
"For those that don't, Jaltek Systems can design and manufacture bespoke interface adapters".
"Also, for volume applications, low cost, dedicated test fixtures can be designed and manufactured in just three-weeks." "Jaltek's boundary scan service is also helping customers use valuable x-ray inspection capacity more efficiently".
"With a runtime of between one to three minutes, boundary scan can rapidly identify the area of the BGA requiring further x-ray investigation." "To conclude, customers employing our boundary scan service take delivery of their qualified products safe in the knowledge they can continue their development and configuration without wasting time debugging problems.".
