"GEL ISOLANTE ADESIVO SALDANTE - GELIAS "WELDING ADHESIVE INSULATING GEL - GELIAS

Questo documento descrive le specifiche caratteristiche innovative del GEL ISOLANTE ADESIVO SALDANTE . Questo prodotto à ̈ la nuova generazione di gel adesivo non metallico, no clean, sviluppato per sostituire la tradizionale crema-gel saldante contenente elementi sferici metallici. This document describes the specific innovative features of the ADHESIVE SOLDERING INSULATING GEL. This product is the new generation of non-metallic, no clean adhesive gel, developed to replace the traditional sealing gel-cream containing metallic spherical elements.

Rappresenta un collegamento innovativo di aree metalliche tramite riscaldamento senza apporto di qualsiasi materiale metallico. I saldanti esistenti hanno un apporto di leghe di materiali metallici., Il Gel Saldante supera il limite tecnologico delle attuali CremeGel Saldanti prodotte per l'elettronica e microelettronica che contengono tante piccole sferette metalliche (i metalli maggiormente utilizzati per questa metallurgia sono : il piombo , lo stagno, l'argento, il bismuto, il rame, io zinco, il palladio) del diametro da un massimo di 80um ad un minimo di 20um. It represents an innovative connection of metal areas by heating without the addition of any metal material. The existing solders have a contribution of alloys of metallic materials., The Soldering Gel exceeds the technological limit of the current Soldering CremeGel produced for electronics and microelectronics which contain many small metal spheres (the metals most used for this metallurgy are: lead, tin, silver, bismuth, copper, zinc, palladium) with a diameter from a maximum of 80um to a minimum of 20um.

Ha la caratteristica innovativa perché supera le indicazioni delle creme-gel saldanti correnti contenenti le sferette metalliche e gli utilizzatori manifestano una criticità tecnologica perché l’utilizzo negli attuali processi di produzione tende a generare una moltitudine di difettosità ( corto circuito). It has the innovative characteristic because it exceeds the indications of the current sealing gel-creams containing the metal beads and the users show a technological criticality because the use in the current production processes tends to generate a multitude of defects (short circuit).

Assolutamente innovativa nella microcomponentistica perché non esistono controindicazioni di distanza tra i pin della componentistica elettronica. Esso à ̈ conducente tra metalli a contatto, mentre altrimenti à ̈ isolante. Innova e risolve i problemi delle distanze tra i Pin, limitazione esistente attualmente con i gel saldanti con sfere di qualsiasi metallo. I produttori di circuiti stampati e della relativa componentistica hanno dovuto frenare il processo di integrazione per questo impatto tecnologico di distanza dei PIN (apparecchiature sempre più piccole con funzioni sempre più elevate,). Absolutely innovative in micro-components because there are no contraindications of distance between the pins of the electronic components. It is a conductor between metals in contact, while otherwise it is insulating. It innovates and solves the problems of the distances between the pins, a limitation currently existing with soldering gels with spheres of any metal. Manufacturers of printed circuits and related components have had to slow down the integration process due to this technological impact of distance of the PINs (ever smaller equipment with ever higher functions).

Consente il metodo in uso con le usuali creme-gel saldanti, consistente nell'applicazione , sul circuito stampato, mediante processo serigrafico, con macchine automatiche o semiautomatiche, del posizionamento dei componenti . Si differenzia per la caratteristica innovativa rispetto alle esistenti creme saldanti con sfere metalliche perché i problemi di adesività fra i componenti e la crema saldante, comportano che il tutto non può stazionare per più di 5\8 ore senza che si completi il processo termico. Con il GEL SALDANTE, l'utilizzatore, senza sostituire i propri impianti ,nà ̈ modificare il processo di produzione tecnologico, ha il tempo di adesività, dopo il processo serigrafico, fino a 48 ore. It allows the method used with the usual sealing gel creams, consisting in the application, on the printed circuit, by means of a screen printing process, with automatic or semi-automatic machines, of the positioning of the components. It differs for its innovative feature compared to existing sealing creams with metal spheres because the problems of adhesiveness between the components and the sealing cream mean that everything cannot be stationed for more than 5 \ 8 hours without completing the thermal process. With the SOLDERING GEL, the user, without replacing his systems or modifying the technological production process, has the adhesion time, after the screen printing process, up to 48 hours.

E’ innovativa perché essendo solubile in alcooli consente il recupero della componentistica elettronica utilizzata nel circuito stampato . It is innovative because being soluble in alcohols it allows the recovery of the electronic components used in the printed circuit.
