For a lot of reasons, home etching of PCBs is somewhat of a dying art. The main reason is the rise of quick-turn PCB fabrication services, of course; when you can send your Gerbers off and receive ...
Each subject of this study ingested two oral test doses of radioactive iron: one in which sodium ascorbate was added before (Sequence 1) and the other after the labeled ferric chloride solution ...
Metals with extremely low rates of allergic patch-test reactions included zinc, ferric chloride, and tin. Reaction rates varied depending on metal salt, concentration, and timing of readings.
There’s no mention of what chemistry [Jarzębski] is using – ferric chloride, cupric chloride, or otherwise – but the heaters and aerator should make etching go very smoothly. There’s a ...

[23] Patch-test ... reactions to thimerosal (0.05% in petrolatum), 74% had positive reactions to metallic mercury (0.5% in petrolatum), and 70% had positive reactions to mercury chloride (0.1 ...
Sodium Chloride is an alkali halide with an fcc crystal structure. The basis is two ions, a sodium cation and a chlorine anion. The crystal lattice parameter is 0.563 nm. The diagram shows both a unit ...
A t-test is an inferential statistic used in hypothesis testing to determine if there is a statistically significant difference between the means of two sample populations. A t-test is an ...
