This article walks you through diagnosing and repairing iPhone 12 Pro Max Wi-Fi issues caused by drop damage, including transferring encrypted chips and addressing missing connection pads on the Wi-Fi chip itself. Follow these detailed steps to restore Wi-Fi functionality effectively.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Defekt-Ph\u00e4nomen<\/h2>\n\n\n\n<p>This iPhone 12 Pro Max arrived with Wi-Fi issues after drop damage. Upon inspection, the internal PCB layers showed cracks, prompting a swap of the encrypted chips to a new board. However, the Wi-Fi still didn\u2019t function.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Fehlersuche<\/h2>\n\n\n\n<p>The iPhone 12 series uses an encrypted Wi-Fi chip bonded with the CPU, making straightforward replacement impossible. Common causes for Wi-Fi issues include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Poor connection in the Wi-Fi chip<\/li>\n\n\n\n<li>Damage to the Wi-Fi chip itself<\/li>\n\n\n\n<li>Inadequate working conditions for the Wi-Fi component<\/li>\n<\/ul>\n\n\n\n<p>Since the chips were swapped onto a new board, the issue likely lies with the Wi-Fi chip itself.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Reparatur-Prozess<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Examine the Wi-Fi Chip Under a Microscope<\/h3>\n\n\n\n<div class=\"wp-block-columns are-vertically-aligned-center is-layout-flex wp-container-core-columns-is-layout-28f84493 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/rewa.tech\/wp-content\/uploads\/2024\/04\/01__Wifi_chip_pads_missing.png\" alt=\"iphone 12 pro max wi-fi issue\" style=\"aspect-ratio:1;object-fit:cover\" title=\"\"><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\">\n<p>The inspection showed several missing pads on the Wi-Fi chip, meaning a new replacement wouldn\u2019t resolve the problem.
