1971-1975

A rudimentary prototype marks the beginning of the history

The founder Enrico Canziani designs an innovative prototype to solve some automation problems within a local company: this marks the beginning of a small craftsmanship that in the following years will turn into Sapra Elettronica.

A static driver for the management of a brake/clutch …. made with a rudimentary printed circuit manually produced with nail polish and acid etching, with two germanium transistors mounted on it. An imperfect prototype that, however, reveals to be a winning solution, starting the story of Sapra Elettronica.

1975-1978

Series production begins, Elca is born

The idea of building a cooperative reality arises. Meanwhile, relationships with first-tier clients are greatly strengthened and a number of cutting edge solutions emerge. The founders feel the need to set up a company and find the necessary funding for the production of equipment in series: the company is transformed into s.r.l. and baptized Elca (Elettronica Cassanese).

1978

Elca acquires value and becomes increasingly tied to its first clients, that are becoming world leaders in their respective fields. Many new electronic management equipment are introduced, first using traditional electronic logic and then introducing the machine language programmed RCA microprocessor.

Equipments that are absolutely state-of-the-art for the period, as competitors’ machines are still fully mechanical. The introduction of electronic controls, especially in quilting machines, is a winning choice. The 1978 Hannover ITMA fair demonstrates the success of this innovative approach.

1980

Elca becomes Sapra Elettronica

The company is transformed into SAPRA Elettronica s.r.l. New important clients are acquired, especially in the field of industrial laundry and textile fabric manufacturing. The company's business considerably expands and the number of operators increases, reaching about 25 employees.

1990

Acquiring international clients

SAPRA begins to develop and produce proprietary systems for the Automatic Test Equipment industry, acquiring new important international clients including Pilatus Aircraft, Logic S.p.A., Alstom, Fiat,  NATO armies and Iveco Group.

2010-2012

From product provider to technological partner

The company witnesses the crisis of traditional clients and the contemporary exponential growth of clients who offer a highly technological product, operating on the international market. New solutions are studied, enhancing system integration and robotics know-how.

A new strategic vision allows the company to effectively face world crisis and generational transition.

High efficiency LED illuminator is provided in 16-mode emitters with stabilized light intensity control so that it can operate with semitransparent materials or to compensate for the working distance; The device can work in a wide range of 1 cm to 100 cm and beyond, 24 V DC 30 mA power. Several modules can be mounted online, without altering the pitch, to illuminate the exact number of photo sensors. On request we can provide modules with different quantities of emitters. It is not necessary to align the illuminators with the receivers with extreme precision.

Devices are normally provided as bare cards; We can provide both construction drawings for anodized aluminum or plastic material containers, as well as the containers themselves.

It is possible (option) to program control sets in order to obtain STAND_ALONE command outputs without the need for remote control.

The device can be reprogrammed in all its parameters via the RS232 interface, without having to be removed from the installation.

With our know how, and thanks to some international agreements, SAPRA has been operating for years in the ATE sector, developing complete systems for the testing of electrical and electronic equipment.

Some of our products in this field:

Cablotest Compact is a cost-effective and compact test device, suitable for wiring and back-panel testing.

Born from the multi-year experience in testing equipment, this product integrates the flexibility of a Windows system, the quality of an industrial construction and the precision of a sophisticated measurement system with quality software and hardware assistance.

The small dimensions and the integration of the 5.7 "color graphic display on the front of the container make the equipment a real bench tool. The Windows operating system assures immunity from viruses, tampering and application stability. Cablotest Compact is extremely easy to use.

The test points are available on din 41612 male contact connectors; it is thus possible to use standard flat cables or special round cables with crimping or welding pin.

Programmable electronic loads.

Loads: active-passive-hybrids from 1 kw to 20 kw.

Adjustments: constant voltage - constant current - constant power.

Protections: Overload - Temperature - High and Low Voltage.

Outputs for diagnostic controls, detection and data storage.

Graphic View, Print, and Export to Standard Formats.

Possibility of networking.

AOI 2000 is a new optical inspection system for THT, SMT and mixed assemblies.

AOI 2000 provides the test program using directly the data of the mounting machine.

The system has software adapters for the most popular P & P brands and component, dimensional and image libraries, useful for quickly and easily generating the test program.

AOI 2000 is also capable of learning a sample card.

AOI 2000 can be equipped with a THT component control camera or dual resolution on SMD components.

Different objectives are also available to cover different control needs.

Matching Patterns or Bit Image Comparisons: The degree of similarity is expressed in percentage. The degree of coverage is very high, however, this method creates several false mistakes as each minor difference (different character, shifted silk screen, etc.) causes an error. AOI 2000 features Pattern Matching with do not care to avoid these false mistakes.

Pattern Matching Don’t Care: Test as Pattern Matching, but with the possibility to mask the zones considered variable. Using Pattern Matching or Pattern Matching with don’t care, it is possible to take advantage of the OR option, ie having more than one reference image for each individual component, so that the case of false mistakes is greatly reduced.

OR function: allows you to have multiple images or comparison strings, in practice it allows you to selectively discriminate different components that can be mounted in the same location. The comparison is considered valid when one of the declared components is found correctly assembled.

The OR number is limited only by available memory; Too many OR slows down the test.

OCR (Optical Character Recognition) / Bar Code: converts the ASCII format into a raster image (camera image); For small components, you can zoom in on the image.

Object: Very fast technique to detect only the presence of an object with different color from the background (fiber). This technique can be used for THT components, such as Resistors, where shape, position, and line values are never in the same position.

PROGRAMMING, EASY TO USE

AOI 2000 is easy to program and does not require highly experienced staff. The software is structured in interactive menus that guide the operator to achieve the desired performance.

AOI 2000 has a component library and component library library. The library can be global, meaning that each library component is stored in a directory in the form of files and represents the base library of each test.

When you associate a library with a component, it is duplicated and rendered inside the test, so that each change and customization only affects the test.

There are some import / export functions for exchanging libraries.

Component libraries for the AOI 2000 optical system consist of a file archive, each containing the unique component information needed to perform optical tests.

The main purpose of component libraries is to expedite and facilitate the test declaration phase as it does not need to redefine the information of the components already in the library.

Checking a pin welding of a component is really easy as the library offers the ability to simply select the type of test to be performed. In fact, it is possible to select the welding presence.

This type of comparison allows to measure at different levels the size of the welding joint with respect to the pin terminal and the welding pad. You can also check and verify the presence / absence of welding; For example, if it is "lean" with respect to the dimensional reference parameters.

MOBILE PHONES KEYBOARD TESTER

SWT is a fully controlled 3 axis CNC, especially designed to test keyboards of mobile phones in a fast and reliable way. The SWT is mainly a bridge powered by step motors. The Z group with micrometric screw, force sensor and measure card is mounted in the probe head on the front side; the endurance structure is mounted on the backside.

FORCE TEST DESCRIPTION

The bridge goes on to UUT; the movement between the 3 axis is free and independent, so to guarantee the fine displacement over the keys, as you need. The color camera assures the accuracy of positionning. The high-resolution camera, combined to the autofocus system, manages the offset UUT position automatically.
The key mechanical commutation is measured by comparing the displacement and the force in real time .

The programmer set the maximum force expected in according to the key characteristic (ex.5,5N) and the maximum key travel (ex. 2,8 mm). The Z-axis pushes down the button up to reach the set force value, then the Z-axis goes up again.

The key points as Fa activation force, Fr return Force, Cm mechanical travel,
Ceð electrical commutation are fully programmed. The system software gives data and curves for each UUT key under test.

ENDURANCE TEST DESCRIPTION

The bridge moves on the UUT along the Y-axis. When the bridge is perfectly on the phone, the Fast Adapter moves down. The descent of the fast adapter is pneumatic through 2 pistons. Conic thorns of reference assure the accuracy between the chassis adapter and the phones.

The layout chassis adapter changes in according to the keyboard type and size.

The test sequence is free; it’s possible to command single, group or all pistons. The test time, the test frequency and the key push time are programmable.
