FUJI NXT O-Ring A5053C

For the SMT industry, Fuji mounter FUJI is a relatively cost-effective machine, NXT belongs to the FUJI FUJI is the masterpiece of the mounter, from 2004 to now in 2014, NXT has been very mature. In NXT's working head, there is an accessory, belongs to the wearing parts, A5053C, also known as A5054X, is an O-ring, also known as sealing ring, used in NXT's H12S working head, also used in the H12 working head, H12HS working head, V12 working head, the working head, also known as the mounting head. So many working head need to use A5053C, A5054X, the most vulnerable to wear is also this NXT accessories, but in FUJI accessories is very small, the unit price is relatively cheap, a NXT mounting head H12S only with 72 A5053C, or A5054X. a mechanical valve SPOOL inside, there are 6 such seals A5053C, A5054X, if H04HHS, H12HS, V12 working head, working head is also known as the mounting head. A5054X, if H04S there are 24. If H08 head, there are 48 of them.

O-Ring

Product name: O-ring

Material number: A5053C

Specifications： dia.1.8X0.7

Use: NXT

How to distinguish between SMT FUJI Fuji original parts and imitation parts:

Original:
Better material, wear-resistant, longer service life;
High precision, good mounting effect;
Smooth nozzle hole, not easy to block the hole;
Reflective effect is good, recognize the nozzle is more accurate.

Imitation:
Poor material, not wear-resistant, shorter service life;
Poor precision, which has an impact on the quality of the mounting;
Smaller suction nozzle holes, easy to plug the holes, resulting in insufficient vacuum, poor pick-up, throwing material serious;
Reflective effect is poor, recognition of the suction nozzle is easier to cause recognition errors.

Share SMT industry must know the problem

1; ECN Chinese full name: Engineering Change Notification (ECN); SWR Chinese full name: Special Requirements Work Order (SWO), must be countersigned by the relevant departments and distributed by the Document Center to be effective;
2; The specific content of 5S is to organize, straighten, clean, clean, quality;
3; The purpose of PCB vacuum packaging is to prevent dust and moisture;
4; quality policy is: comprehensive quality control, implementation of the system, to provide customers with the quality of demand; full participation, timely processing, to achieve the goal of zero defects;
5; Quality three no policy: do not accept defective products, do not manufacture defective products, do not flow defective products;
6; QC seven practices in the fishbone to check the cause of the 4M1H refers to (Chinese): people ﹑ machine ﹑ material ﹑ method ﹑ environment;
7; The composition of solder paste contains: metal powder, solvent, flux, anti-drift agent, active agent; by weight, metal powder accounted for 85-92%, by volume, metal powder accounted for 50%, of which the main components of the metal powder for the tin and lead, the ratio of 63/37, melting point of 183 ℃;
8; Solder paste must be taken out of the refrigerator to rewarm when it is used, the purpose is to let the temperature of the refrigerated solder paste return to room temperature, so as to facilitate printing. If it is not warmed up, it is easy to produce defective solder beads after the PCBA into the Reflow;
9; The machine's file supply mode: ready mode, priority exchange mode, exchange mode and quick connect mode;
10; SMT PCB positioning methods: vacuum positioning, mechanical hole positioning, bilateral clamp positioning and board edge positioning;
