It is necessary to enter the body size and element information in part data. The reference point for the part is the part center. If the tip of a lead is not square by design then this information must be set in part data so that it is not detected as a defect. Note that… Continue reading about Vision Type 72 HEMT (Supplied at 0 degrees) and Vision Type 73 HEMT (Supplied at 45 degrees) For Fuji NXT

Enter the body size in part data. There is no need to enter element information. Note that projections such as leads are included in the body size. The reference point for the part is the part center.
It is necessary to enter the body size and element information in part data. The reference point is the body center with vision type 70, while the reference point is the part center with vision type 75. Create separate element data for leads of different length and width. If the leads have a large cuts… Continue reading about Vision Type 70 (75) Power Transistors For NXT Vision Types Of Part Data Settings On Fuji NXT
LED lenses are made of resin. Therefore, the lenses sometimes adhere to the top cover tape due to the resin’s stickiness. When the cover tape is peeled from the carrier tape, the LEDs tilt within their cavities, resulting in mounting failure. It is impossible to eliminate the stickiness of the lens. Please refer to the… Continue reading about 3-3-2. Change The Peeling Angle On 3-3. Problem 3: Led Tilting Within The Cavity Due To Its Adhesion To The Top Cover Tape by Nichia

Correction of the Absorption Point: Above screenshots stand for Panasonic CM Mounter(left one) and Yamaha YS Mounter(right one). Please adjust the mounter to ensure that the nozzle should absorb the correct point on the LEDs. The absorption point can be corrected with the image recognition unit by aiming at the center of the hole on… Continue reading about 3-2. Problem 2: Absorption Error Due To Air Leak
3-1. Problem 1: Damage to the lens during the mounting process Nichia establishes the optimal absorption method and the optimal cavity shape/size for each LED with a lens. In general, there are two absorption methods; one is the “nozzle insertion system” and the other is the “non-insertion nozzle system.” 3-1-2. Non-Insertion Nozzle System When the… Continue reading about 3-1-2. Non-Insertion Nozzle System Of Problem 1: Damage To The Lens During The Mounting Process For Mounting Techniques By Nichia

Many LEDs with a lens have been developed for higher performance. Such lenses are mostly made of resin; when external stress is applied to the lens, some are susceptible to damage, leading to abnormal optical characteristics, and others are susceptible to wire breakage, leading to abnormal electrical characteristics. Therefore, applying external stress to the lens… Continue reading about 2. Mounting Failures in LEDs with a Lens by NICHIA
As LEDs have recently been miniaturized and highly-functional, higher mounting technologies are necessary for them. It has been difficult to mount such advanced LEDs because of the lenses and the smaller absorption area. Improper mounting will affect the function and the reliability of the performance from the end product. To manufacture high-performance lighting fixtures with… Continue reading about 1.
