Stella original measuring system (ST/LST series) by the CAD data match-up method
Inspection system with high cost performance gLST Seriesh has been released
By new structure design, we could succeed to reduce system cost
Low cost inspection system which is possible to be customized correspond to needs of field has come into existence
@Expansion of function, customization ability
It introduces original element technology which is stored for many years while keeping structure of the existing system gST seriesh. It's possible to correspond to needs of field flexibly.
It's possible to prepare an inspect system correspond to needs of field flexibly by expansion of function and customization. For example, it's possible to use as a system which find out caribration value in the time of correspond to fine pattern by use of data caribration. Also, it's possible to inspect while recording data as a visual check assisted system. Of course, it's possible to operate some systems simultaneously.
ACompact, lightweight, and use any locations
LST series can be placed with use any location because it's compact and lightweight. For example, it can be placed on the desktop. Furthermore, it can be placed any place because of silent design.

The latest model of LST seriesFLST3040G
LST4050G is a low-cost model of measuring and AOI system. It is possible to customize functions upon request of field needs.
Concretely, it is possible to measure and inspect external dimensions of device, pitch of holes, slit width, corner R, external dimensions and angle of hole, and so on.
Also, it is possible to measure hole diameter of through-hole and non through-hole for NC hole application use.
Besides, it can be set up in any place because of compact size and light weight. For example, it can be used as a desk-top machine in the desk.
In general, while measuring work is done, it is necessary to prepare a measuring program such as teaching, input of measuring point, and so on. On the other hand, in LST3040G, it is possible to auto-manufacture a measuring program corresponds to the CAD data. Therefore, preparation of measuring is not necessary. Also, it is possible to treat a set of work from preparation of data to AOI continuously, because it is operated simultaneously with our software (Router Vision).
£Before calibration(left), after calibration(right)
Data analyzer system for etching calibration work appears on the scene
We have developed LST3040A system as an added value system of LST series, too.
It's an ultimate data analyzer for etching calibration work. In this system, first of all, a real substrate is wet-etched by making use of the CAD data (Gerber data). And then, calibration value is simulated by comparison of its etching result and the original CAD data. Customer wet-etches the substrate correspond to this feed-back result. As a result, etching treatment is optimized. Therefore, it is defined as an optimized tool for etching treatment.
Of course, in this system, it's possible to add measuring and inspection function as optional function.
£Etching simulation @
This is a first etching simulation sample. Users prepare some samples in advance.
@Etching treatment is performed by making use of the normal data (the CAD data), to estimate etching property.
AEtching result and some simulation results are compared, so that, an optimized data is selected in accordance with its result.
BThe original data (the CAD data) is calibrated automatically by feedback offset treatment which is gained in accordance with the original data and simulation data.
CEtching treatment is performed in accordance with feedback offset data, and then, its result is analyzed.
