A brilliant solution for some tricky repair challenges
This is not a replacement for standard solder but a specialist product for particular scenarios where the much higher temperature of regular solder (320 degree tip temperature typically), is higher than the material being soldered will tolerate. This is a brilliant and cost-effective solution for scenarios where you want to repair things like mylar or kapton ribbon cables, where the plastic won't take standard solder temperatures. In testing with some standard copper foil, the paste bonds strongly to the foil using a soldering iron tip temperature of 170 degrees, and this is well below the maximum temperature for these plastics at least for fairly brief periods of time. In scenarios where the base metal won't tin with this solder (I have not tried anything other than clean copper foil at this stage), repair with adhesive copper tape which is then connected electrically using conductive silver paint (which does not have any adhesive bonding strength), will provide a solderable surface. Once I am comfortable with the product, I intend to repair some vintage calculator keyboard assemblies, where a top and bottom layer are bonded, initially through conductive adhesive which has now failed. The plastic used does not melt at the tip temperature used here. Although I have not tried this, it ought to be possible to do reflow soldering using SMD components in a domestic oven set to around 170 degrees. Note that this is quite a brittle solder and so wouldn't be suitable for scenarios where there is significant flexure or vibration, but, again, as I said, it's a specialist product.

Works for solder repair
It does what it is meant to do with hot air or iron

It's solder
A bit too stiff to use with small components, other than that it does the job.

Useful low temperature solder paste
Useful low temperature solder paste for getting into tight corners oin printed circuits and also useful for temperature sensitive electronics.

Paste ließ sich hervorragend verarbeiten und liefert tolle Ergebnisse! Die Konsistenz war genau richtig, nicht zu fest und nicht zu flüssig. Ließ sich gut selbst auf kleinste Lötpads (z.B. 24-Pin USB-C-Buchse) auftragen mittels Schablone. Jedoch härtet die Paste anders als mir bekannte Pasten wirklich bombenfest aus im unverlöteten Zustand! Ich habe das Zeug wirklich nur mit enorm viel Aufwand aus der Stencil wieder rausbekommen, Lösungsmittel etc. hat nur wenig gebracht. Am besten direkt nach dem Auftragen das Stencil reinigen...

Die Gruiqrd Spritzenlötpaste ist eine hervorragende Wahl für niedrigtemperatur Lötarbeiten an empfindlichen Bauteilen. Sie bietet eine gute Lötqualität und eine einfache Handhabung, insbesondere durch die praktische Spritzenform. Die bleifreie Formel und die niedrige Schmelztemperatur machen sie zu einer umweltfreundlichen und sicheren Option für präzise Lötarbeiten. Besonders für BGA, SMD und SMT Anwendungen ist sie eine empfehlenswerte Lötpaste, die auch für Hobby-Elektroniker und Reparaturarbeiten in der professionellen Elektronik empfehlenswert ist. Klare Kaufempfehlung!
