PCB Design Guidelines for 3x3 LGA Accelerometers © Kionix 2015 10 July 2015 Page 1 of 11 Introduction This technical note is intended to provide information about Kionix’s 3 x 3 mm LGA packages and guidelines for developing PCB land pattern layouts. These guidelines are general in nature and based on recommended industry practices.

由於DFN 的貼裝高度較低, 建議使用低殘渣,免清洗 type 3 焊锡(SN63/Pb37 or SAC alloy) 。 回流焊焊接後( 包含手動焊接及回流焊焊接), 在焊接後都不允許沖洗PCB板。 所以建議客戶使用“免洗”型錫膏。 焊接允收標準請參考IPC-A-610規範。 IPC-A-610 規範8.3.5中, SOT/SOP/LQFP 系列產品焊接相關判斷標準如下表Table 8-5。 適用class:class 2( 消費性電子產品適用)。 IPC-A-610定義最大側面偏移A 不可大於50% 腳寬W,或不大於0.5mm,取兩者間較小者為標準。 IPC-A-610定 …

You can now order the PCB's and all other stuff yourself. The PCB files (Gebers) can be uploaded to any PCB Manufacturer (e.g. JLCPCB) and be ordered for very cheap.

PCBs for various keyboards like the Nyquist, Iris, Viterbi, and Levinson.

2024年6月25日 · High quality PCB can withstand re-work ; Enables SMD parts to be used with a breadboard, perfboard, or protoboard ; 0.1" pitch holes for standard headers

Startup guide for the WannaBe Engineering 3x3 macropad: First off, thank you for purchasing this PCB, and I hope it works out well for you. I'll do my best to provide clear instructions, but if it's a bit hard to follow, or flawed in any way, please let me know via the email provided at the bottom.

SHIELD KEYPAD 3X3 ARDUINO: This project will allow us to open an electric door by means of a key, so if it is correct it will turn on a green led, but if it is incorrect it will turn on a blue led, we will press a 4 digit key on our 3x3 matrix PCB by push button and we will t…

The following figures illustrate an example of proper PCB via and trace placement. Obviously, each product will present its own physical limitations for accelerometer placement and trace routing. Therefore, these guidelines are general in nature.
