Installatie

🔴 Moeilijk — micro-soldeerwerk met hete lucht (350-400°C), flux, soldeertin en stencil. Niet voor doe-het-zelf — vereist ervaring met chip-rework, board-level reparatie en ESD-veilige werkplek. Laat installeren door een gespecialiseerde micro-soldeerservice.

Veelgestelde vragen

Kan ik dit zelf installeren?
Nee — chip-vervanging vereist hete-lucht-soldeerstation (BGA rework), stencil, lood-vrij soldeertin en ervaring met board-level repair. Onveilig zonder de juiste apparatuur en kan andere componenten beschadigen.

Welke gereedschap is minimaal nodig?
Hot-air rework station (350-400°C), preheat-plaat (optioneel), microscoop of vergrootglas, ESD-veilige werkplek, flux paste, lood-vrij soldeertin 0.2-0.3mm en BGA-stencil voor reballing.

Is dit een originele chip?
Mackenners levert door de leverancier gecontroleerde IC-componenten. Voor mission-critical reparaties (Face ID, secure-enclave) raden wij aan eerst te overleggen met je reparateur over OEM versus aftermarket.

Excellent critical history
Format: Kindle
A very thorough and important work, astute view and scope of a history of a philosophy and its most sweeping consequences in the modern era. However, this also tends to be postcolonialism in a nutshell and is, from that view, an argument that goes back to at least the 1950s in academia and further if you're looking for straight up anticolonial voices of the past. Also I don't like the way the author cites sources, often giving the reader no clue as to the specific primary source being referenced, instead referencing an entire volume or a generic secondary source. Lastly, the book falls a little short as an interrogation of the marketplace itself.

Liberals run and cower, Losurdo is here to destroy you
Format: Paperback
First the physical product review: The book came in a brand new condition with no wonky missprints or anything. Good quality paperback. Now the contents: This book is a complete vivisection of the liberal ideology. Losurdo takes you to the earliest foundations of the liberal ideology and lays bare in great detail its positions and internal contradictions. He studiously walks you through the evolution of the ideology within the context of the times to give the reader a full understanding of how the "great" liberal theorists of the time attempted to navigate the sociopolitical environment, and how their interpretations in turn affected (and continues to affect) the real politick. From the French Revolition to Nazi Germany Losurdo exposes the Liberal ideology for the exclusionary and exploitative sham that it is with Liberal theorists own words and liberal governments' historical actions. If you ever heard the expression "scratch a liberal and a fascist bleeds" this book will fully explain why. Truly a must read that I cannot recommend enough!

The subtle counterrevolution mixed into the liberal revolutions
Format: Paperback
From the time of Marx/Engels the critique of liberalism has always been set against the heroic tale of its association with the triumph of democracy. As the author here makes clear in close detail the history of the liberal framework is not so transparent, and this can be seen in the way the world of Locke emerges from the radicalism of the English Civil War with a liberalism that will condone slavery. This legacy is inherited by the American Revolution and leaves the whole onset of its democracy ambiguous. This is the classic 'bourgeois' revolution and is what lead to the critiques of the socialists who looked back at the inner failure of the democratic revolutions behind their surface success.

A Must read for all Americans and those who appeal to the American model
Format: Hardcover
Certainly everybody who uses the words, 'freedom' 'liberal' 'democracy', as so many do so loosely, and so many who appeal to the "New'World" model do, should read this; and then take stock of the double standards and hypocrisy that existed in the past, and which still thrive today, based on discredited myths from the past two or three centuries.

A Challenge For All Liberals
Format: Paperback
I thought the book was well-written, impeccably sourced, wide-ranging, and with a thesis that can't help but make you think. Well worth your time.
